ADBTuner has been working extremely well for me with a Uraytech encoder ($198 on Amazon) which can do 1080p60 - I purchased this encoder because, at the time, it was one of a few that were cited as working with HDMI for Channels and it does 60fps - the 4K version just downscales the image to 1080 anyways - with the "go" program and HDMI for channels solution, I had frequent A/V sync. issues and also had to repair recordings with incorrect lengths by doing a manual "fix video timestamps" afterwards -
With ADBTuner and a nightly re-boot at 4AM - all recordings have been clean - I've even changed the encoding settings from CBR to VBR and lowered the bitrate from 10000 to 8000 and it just works - one thing - I contacted URaytech and got the latest firmware for the encoder - the original firmware actually had a virus that got detected when I downloaded it - I am using an Onn TV 4K by the way via WiFi and I have never seen a glitch so haven't needed an OTG ethernet adapter
Now that more encoders have been tested, I might consider purchasing a 2nd less expensive model as long as someone can vouch for it and it has to do 1080p60 h.264 (h.265 optional)
Also, BTW, maintenance is a breeze running ADBTuner on Unraid, which has the capability to check for updates, inform me and update the docker (but I realize most of you don't have an Unraid server)
The only thing that I am wondering now is when will my YTTV channel URLs (links) expire?
If I have to go through trying to nail down the Fubo scheme again...
