I only have the standard FireTV 4K stick and all my programs are ATSC 
1.0 OTA either 1080i at 30Hz or 720p at 60Hz MPEG-2. For recorded playback, 
the mythfrontend is very watchable for us except in very high action 
sequences. But if it's recorded we normally just use Leanfront since 
it's damn near perfect.  I use mythfrontend for editing and setting up 
scheduled recordings. It's much easier for that.

What leanfront doesn't do well is watching a program while it's being 
recorded. I've found for a long time that if I start watching an NFL 
football game 30 minutes after it started recording it works until I 
start trying to skip a commercial. It sometimes goes backwards after it 
adjust the end time which changes after you pass the 30 minutes in my 
case mentioned above. I have not found anything in the adb log that 
tells me anything useful.  That's one reason I use mythfrontend for 
watching behind real-time on a recording.
