Previously, for the past 6 years, our household used a “Tablo” as our in-home OTA DVR solution. For that purpose, it worked fairly well. I won’t go into any of the downsides, but the final deal killer was the inability to access it remotely using Roku devices. No matter how many router tweaks and settings such as port forwarding I tried, Roku just couldn’t access it. The only thing that worked was using a smartphone. All we wanted was the ability to access our local news broadcasts and sporting events when out of town. We thought we had found a solution by subscribing to “YouTube TV” which provides local channels as part of the package. Imagine our disappointment when on our first trip out of town, we could not get any of our hometown stations but instead those of where we were at the time. Upon our return, I resolved to finally replace the “Tablo” with a SiliconDust “HDHomeRun Flex 4K”. Operationally, much like the “Tablo”, you connect an OTA antenna to the unit, connect to your home network and then power it up. One of the nice things about the “Tablo” is that you can connect to your home network wirelessly. The “HDHomeRun” requires a wired ethernet connection. This meant we would have to run ethernet cable from our router to where the unit would reside. Fortunately for us this was something we did last year for different reasons but in the process, the “Tablo” was connected directly as well which greatly improved its responsiveness and stability. Unboxing the “HDHomeRun” and connecting it in place of the “Tablo” took only a few minutes. I used the “HDHomeRun” app on my android phone while connected to the same network to finish up firmware upgrades and channel scans. The “HDHomeRun”, when connected to our attic antenna, picked up 52 local ATSC 1.0 channels and 4 ATSC 3.0 stations. Now, the main reason we selected the “HDHomeRun” was its ability to integrate with our “Plex Media Server” which we have had operating for years. Within just minutes, the “HDHomeRun” was setup within Plex which, as part of our lifetime pass, provides a guide for all of the channels the “HDHomeRun” found. Plex also provides native DVR support so no additional storage devices or fees to SiliconDust for their DVR functionality. What Plex won’t do is decode AC-4 audio (blame FFmpeg) which is what the ATSC 3.0 broadcasts come with. Not a huge problem since all of the ATSC 1.0 audio channels work just fine. We anticipate that Plex/FFmpeg will provide the AC-4 decoder eventually as ATSC 3.0 adoption picks up, but the main thing is, since Plex is a server, we can access it remotely which means all of our local channels are available remotely as well. “HDHomeRun” also has a Windows 10 app which was downloaded to test. That worked great and after downloading a couple of drivers it said it needed, including a 99 cent one from Microsoft, I was able to play the ATSC 3.0 channels with audio as well. Some users have complained about channel changes taking a long time. For us this is 2-3 seconds. I challenge anyone to go from one YouTube or Roku channel to another much faster. All in all, to date, this change over has worked out well. It picks up all of the local free channels we could ever need. Subjectively, we also think the image quality is great. If I had a wish list, it would be that the “HDHomeRun” apps provided more native info and/or metadata about each channel such as the kind of audio track being listened to and the video resolution. Kind of like YouTube providing “Stats for Nerds” on each of its videos. We’re not sure if we are future proofed on the ATSC 3.0 roll-out but that was not the only or even main part of the reason for our purchase decision. What we wanted is what we got, and it works very, very well. Review: I had an Internet/TV/Phone bundle through Verizon that I've had for years but I finally decided to "cut the cord" because I was tired of paying for TV service that, honestly, I rarely used. We have a couple of streaming services that we watch purposefully, and we only ever used the TV service for background noise or to watch live TV during special events or local news or things like that. So I dropped the bundle, increased my Internet speed, and ended up cutting my Verizon bill almost in half. As part of that decision, I decided to get this HDHomeRun box so that I could still get local broadcast stations for local live news and event coverage. I paired it with this antenna: https://a.co/d/4Xrc74l The box is in my basement, connected to my core switch. The antenna is on the second floor of my house near a window. I reused some coax I had in my house to connect the two - making sure that nothing else was connected to the coax - no splits or anything. This box is great. My Plex server found it immediately and was able to perform a channel scan and pull guide information no problem. AND even though I'm using it with Plex, you don't have to. As long as you have a device on the same network at the HDHomeRun box with the HDHomeRun app installed, those devices can address the box directly without needing to go through Plex at all. I was hesitant to buy a box with four tuners in it - why would I need four tuners? I discovered the answer during the eclipse on April 8 - I had Plex set to record two different news broadcasts during the eclipse while I watched a third broadcast using the HDHomeRun app on my Chromecast with Google TV. This engaged three of the four tuners in the box, and it performed perfectly. I will point out - since some of the literature is unclear - that all four tuners are capable of ATSC 1.0, but only two tuners are capable of ATSC 3.0. In my area, only two channels are broadcasting in ATSC 3.0 right now, but even those channels are broadcasting in both for the time-being. But for most folks, ATSC 1.0 is all you need at the moment, and having four tuners that can pick that up really makes it useful when you want to watch or record multiple things at the same time. Set up is easy - plug the box into your network. It will check for firmware updates on its own, and you can use the web interface to apply those updates if you wish. I gather that it essentially uses DLNA to share the media streams, so anything on the same network can use the box. Also, if you're using it with Plex, the recommendation is to assign a static DHCP lease to the box because if the address changes, Plex may have to set it up all over again. This is not a requirement if you're just going to use the HDHomeRun app, since the app looks for the box via broadcast each time you open it. This box is easy to use, works with a wide variety of devices and applications, and is practically plug-and-play in terms of setup. I am very pleased to have it. ## Features - NextGen TV certified - watch live TV on multiple devices simultaneously throughout your home with our Multi room Multi user network tuner solution - Full whole-home DVR by connecting a USB hard drive (requires paid TV guide for DVR record) - ATSC 1.0 content is compatible with Android, FireTV, AppleTV, Roku, Sony, XBox, iPhone, iPad, Win10/11, Mac - ATSC 3.0 DRM-free content is compatible with Android, FireTV, AppleTV, Roku Ultra 4800X and newer, iPhone, iPad, Win 10/11, Mac.

But You can only watch up to 2 simultaneous 3.0 channels (or can record 2 atsc 3.0 channels if you are using the DVR feature of the HDHomeruns) A few of the very newest (typically OLED) TV's are able to be directly compatible to play this back (the AC-4 audio which is a Dolby format that is NOT commonly supported yet) or as others are noting, you can tune to and play the 3.0 broadcasts on most of the HD Homerun apps on some (not all) devices. NVIDIA shield probably the best bet. Interestingly the Channels App downloaded with NVidia sheield or several NAS (network attached storage) devices that support that application can now record/playback the format and handle the audio as well. **Q: What is the difference between this flex model and the hdhr5-4k?** A: The FLEX 4K is a CONNECT 4K with a USB port for optionally connecting a hard drive. With no hard drive plugged in it works exactly the same as a CONNECT 4K. **Q: What codec is the content streamed in?** A: There is at least one streaming player that supports AC-4 audio, the Roku Ultra 4800. It has to be the 4800 model, as that is the only Roku that supports AC-4 audio. **Q: I have a 1 tb hdd, 3 non-smart tvs with firestick, 3 avr audio systems with hdmi, and 100+ gb/s wifi. what else do i need to make this work?** A: You need 1) an over the air (OTA) antenna, 2) an ethernet cable to connect the HDHRun to your router or ethernet switch (no WiFi), and 3) Your hard drive needs to be connected to same home network if you intend to use it to DVR OTA TV programs. Keep in mind the HDHRun is an internet dependent system. If your internet goes out, the HDHRun unit won’t work at all. I have both the Tablo dual, and an HDHR 4k flex unit. I prefer the Tablo since I can watch live and recorded TV while the internet is down (home network must be running though). You also connect your hard drive directly to the Tablo via USB, and it can use either WiFi or ethernet hardwire to connect to the app. The Tablo app you download from the app store will find and connect to it - same as the HDHR appa. I haven’t tried AirTV yet. It looks promising, and will interlace the OTA broadcast with Sling. The HDHR is a good quality device, but has several aspects I find annoying. 1) I already mentioned that it MUST be connected to the internet before the home screen will come up. 2) Hardwire ONLY connection to your home network. 3) Access to the channel scan utility is not within the app. You access the channel utility through the device’s IP address. 4) You have to pay Silicon dust a subscription ($30/yr) to use the DVR function. Tablo only requires a subscription to get a 2 week grid guide - else you only get 24 hours look ahead. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***N on 11 July 2022* This is kind of lengthy...

My Connect Duos still performed but I decided to purchase a 4 tuner model to free up an internet outlet. Performance: The tuner pulled in available channels for my area. I used it with a roof antenna at a house and with some indoor antennas at an apartment. The indoor antennas drive me crazy because they are so sensitive but my HDHomeRun tuners still pick up whatever they bring in. Channels look the same from HDHomeRun as they do with the native Samsung tuner. I love the updated guide design in Live view. DVR Service: I began using the HDHomeRun Connects years ago with Windows Media Center on a Windows PC as my DVR (miss you WMC). I purchased one Duo then later purchased another one a year or 2 later. Once WMC was retired, I switched to the HDHomeRun DVR service for $35 per year. With the service, we are basically paying for the guide data, not the DVR service. It works okay and I like that it now shows upcoming tasks. I also have a Plex media server on my pc. I tried the Plex DVR but quality was inconsistent. I only have to go into the DVR part to schedule on demand recordings. I like that it allows you to schedule single episodes and the guide even includes the Season and episode number in the Discover section when you select airings to record if you do not want the whole season. How I Watch: I still have an antenna connection to my main living room Samsung TV so I watch Live TV from their native tuner. I use the HDHomeRun app or the Channels app to watch live on my AppleTV in my bedroom. The rest of my TVs use either the HDHomeRun app or the Plex app to watch Live TV. This has been working for me. I also tried Kodi as my front end and it did work okay finding the HDHomeRun tuners but I since moved to Plex for my media server. Replacement heads up: I disconnected one Connect Duo then connected the Flex 4K and set it up. I confirmed my channels and DVR was still good. Next, I disconnected the 2nd Connect Duo. At that point, my schedule DVR tasks disappeared and I had to set them back up again. Some of my shows do not have airings right now so I will need to wait to set them back up. I noticed it did not record its tasks the first two nights. When I troubleshooted, I found the app no longer showed me as an active DVR subscriber. You must go the the Account Details and log back into to your account and add your DVR activation key. I wish that was clear somewhere! Upcoming Tasks: I like this window is available on the Tasks tab to see your upcoming scheduled recordings. I don't know how new that is or if I missed it all these years. This will help me manage my computer's CPU resources with a resource intensive program I run on the same PC I run my HDHomeRun DVR software on. I can pause the other program if needed while recordings are in process. ATSC 3.0: I am okay with this feature not working yet. This is not SiliconDust's fault and I personally have signed several petitions to keep broadcast tv free and available and with ATSC 3.0 available for all since the airways belong to the public. Though I don't use it, I like these newer models have the ability to just connect a hard drive to it to record without a computer. It is a shame our TVs have this capability but it is not available in the US. Overall, I recommend HDHomeRun devices and I am glad they allowed me to easily cut the cord years ago. I conducted a 2 month review prior to cutting the cord and found most of the tv shows I watch are on the major broadcast networks and I like I did not need a device for every tv as some other tuner companies required back then. If you are struggling with the DVR aspect of it, perhaps try a different front end like Channels but it costs a bit more. ## Frequently Bought Together - SiliconDust HDHomeRun Flex 4K ATSC 3.0 NextGen TV: 2/4 Tuners HDFX-4K - SiliconDust LPF-608M LTE Filter for TV Antennas USA 2020 Standard 600/608/618MHz - Antennas Direct ClearStream 2V Indoor Outdoor TV Antenna UHF VHF Multi-Directional, 60+ Mile Range, 4K 8K UHD, NEXTGEN TV – w/Reflector, 20-inch Mast --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/372992399-silicondust-hdhomerun-flex-4k-atsc-3-0-nextgen-tv-2](https://www.desertcart.tn/products/372992399-silicondust-hdhomerun-flex-4k-atsc-3-0-nextgen-tv-2) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
