[mythtv-users] Jittery Video on LiveTV & Playback Via M10000

Sorry about not changing the sbuject last time. I know it makes it hard
to folow threads.
I went back and looked carefully through the playback setting options.
There is an option for libmpg2 but none for XvMC or Via. Trying the
libmpg2 option improves things... the jittering goes to a 4 second cycle
from the previous 2 second cycle. This gives me hope for the XvMC
options, if only I could find out why they are not displaying.
I am using Gentoo 2.6.12 r10 which has native Via modules in it, but the
DRM module is not compatible, so I am using the 20050807 version of the
x11-drm module. Both the libXvMC and libviaXvMC modules are in /usr/lib.
Is the problem possibly in my xorg.conf options? Should I be loading
viaXvMC or XvMC in xorg.conf? I'm including a list of lsmod and my
xorg.conf in case they are a help.
I really appreciate your help on this. I'm lost at this point.
Roger
