I'm using a Tablo as I write this and it does have its issues. With captions enabled, the Roku device sometimes runs out of memory and crashes. I have no idea why. I think it only affects watching live TV. Recorded programs don't have the problem. I'm thinking of trying it on a non-Roku device like a Fire stick. I wasn't happy with the Tablo app on Android streaming device.
Another thing I use is a Silicondust HDHomeRun box. Its Roku app has its own issues and I've never explored its recording capabilities other than pairing it with the now unsupported Windows Media Center running on a PC. Recording is must for me and I watch little to no live TV.
There may be other similar products out there, but it seems like less and less people are watching OTA TV, so there's not much of a market anymore. Those are the two I've tried and I'd have a hard time recommending either one paired with a Roku device. One thing to keep in mind is that if all four TVs are going at once you'll need a device with four tuners if everyone wants to watch something different.
I appreciate the information. I will never have four television going at the same time. There is only two of us that live in the house to start with. The majority of the time we are watching the same thing on the same television. I would say that at the most two televisions might be going on at the same time.
I contacted Silicon dust HD and they basically said I would have the same issues with them because the problem is with Roku. Which was very strange to me. Here is what Silicon dust told me (below). I hope that Roku monitors and sees this reply.
Dman1, the issues with Tablo's and SD's Roku apps are absolutely because of the significant limitations of Roku devices and, more importantly, the Roku "OS". The Tablo and SD developers have probably done the best they can, but Roku couldn't care less about anything that doesn't make them significant ad and/or subscription revenue.
Had anyone tried the AirTv2 with the Roku? https://www.airtv.net/products/airtv2/ I know it will work with Sling TV, because that is advertised. I also have read that a person doesn't have to have sling for it it work. I just don't know how well it works on a Roku device?
I've had an HDHomeRun 4K Flex for easily a couple of years. While I have the HDHR app on my Roku and Shield devices, I don't really use it for OTA watching. It's mainly for my HTPC to record OTA broadcasts, after which I edit out the commercials and store on my media server. But I have my main antenna connected to almost every TV in the house, so it's not really necessary to use the HDHR to watch something on any of them.
That said, it's certainly possible to use the app on all of my devices to have the same channel displayed on multiple TVs. My box has four tuners, and I'm assuming that if I have multiple TVs set to the same channel they would all use that one tuner. I don't use the HDHR recording function, as I use my HTPC for that, which is running J River Media Center. It can use up to all four tuners at the same time, if I actually wanted to record four different shows at the same time.
Silicon Dust has stated in the past they don't put a lot of effort into their Roku app. I think it's because it uses a different programming language that they aren't as adept using as what they use for Android devices. But I still have no issues watching any of the OTA channels available on my HDHR on a Roku or Shield. And for ATSC 3.0 stations, the Roku is actually the better device to use, since the Ultra 480x models support AC4 audio, which is the standard for ATSC 3.0.
