[mythtv-users] MythTV 29.1 nVidia video jump hesitation with 5.15 kernel

[Tom Dexter]

This is a tough one, and I tend to doubt anyone will have any ideas,
but I figured I'd throw it out there:

For reasons I won't get into, I'm still running MythTV 29.1. This is
under Gentoo and the frontend is an x86 (32 bit) machine with a GT 430
nVidia card, using nvidia-drivers-390.147, and using vdpau. Currently
I have both the 5.10.93 and 5.15.16 Linux kernels installed. When I
use the 5.15 kernel...and ONLY with that kernel...I'm getting odd
video/audio hesitations when jumping forward or back, and only in
MythTV. That is, I can't reproduce this in xine or mpv. This occurs
both with TV records as well as h264 videos in browse mode reading
from the local disk.

Specifically, when I jump forward or back, there's a momentary
hesitation before the audio kicks in, and during that short time, the
video gets a little wonky, like it's slowing down for a second. In the
5.10 kernel everything's fine. Sort of really sucks. For now I'm just
sticking with the 5.10 kernel. If anyone has any ideas I'd appreciate
it. Thanks!
