I may have to update my thinking on the RPI4 as a mythtv-frontend. I
found the 8-20-2020 Raspberry PI OS 64bit lite version and installed it
on an SATA SSD on USB3. I then put xserver-xorg with no-recommends
installed and then xfce4 minimum.
I installed my dependencies without ansibe because of the missing
packages in 64 bit. And then compiled mythtv from source. Version v31-0-91.
Not thinking I ran it in the Desktop environment and it worked a little
better than it did previously on the same saved recordings.
When it dawned on me to run from the console without a desktop
environment, I installed pi-utils and ran ./run_mythfrontend.sh on a 4K TV.
The horizontal tearing that I had experienced before was gone on MPEG2
recordings and liveTV. So I don't know if it's the move to
fixes/v31-0-91 or whether raspberry PI OS 64 has improved.
I also noticed that VLC on H.264 and streaming from HDHR tuners was very
good. That's what got me to try mythfrontend on a 64bit PIOS on the RPI4
I used the OpenGL Normal profile with Standard, 4 CPUs, Medium
