[mythtv-users] PVR250 + TVWonder = jerky FIXED

[Chad McQuinn]

Just a note for the archives, really, that what seemed to be the problem
with jerky playback was the redhat kernel. Recompiling with stock source
from kernel.org (without the low-latency/preempt patches) also solved the
problem. I am having a different one now, but I'll post that in a separate
thread.
