<p>I have tried just about every combination, but best results seem
to be with standard, 4 CPUs, OpenGL decode and deinterlacers. A
lot of people might find what I can jerky acceptable. But with too
much time on my hands I've done way too much comparison on worse
case videos. I find Nvidia GT 1030/710 cards in Core i7 PCs to be
flawless. I find the Nvidia Shield TV to be almost the same if not
exactly the same. FireTV 4K is right there also. RPi3s are good
with LibrieELEC Kodi but I'm not a great lover of Kodi interface.
But for mythfrontend on RPi4 I always find some part of an action
scene that messes up a little and that bothers me.</p>
<p>When I travel in my RV, I take a RPI4 mythtv combo and it works
okay enough for that but at home I just use Nvidia Shield. It's
too convenient and runs all my streaming services.</p>
