[mythtv-users] XvMC works on mplayer, not on myth

[Ben]

Its a basic question, but somehow I haven't found the answer. How does
mythfrontend play a video? Can I tell it to use mplayer? (top shows that
mythfrontend is using the cpu when its plays a video, so it isn't
spawning another app for the video, right?). My little computer can't
handle HDTV without XvMC, but I can't get mythtv to use XvMC. I've got
XvMC working fine on mplayer and xine. But when I try to play a recorded
video when myth is configured to use xvmc, I get "unable to initialize
the video"

I'm running debian sid with the binary nvidia driver (1.0-8776) for my
GeForce4 MX graphics card. I'm running mythtv-0.20svn20071022 (from
http://www.debian-multimedia.org). Below are the (I hope) relevant
messages from mplayer (working xvmc) and mythfrontend (borking on xvmc).

Any help great appreciated.

Thanks,

Ben

Works great, cpu at 40%. But from mythfrontend, I get:

Any ideas?
