[mythtv-users] MythTV runs smoother with libmpeg than XvMC?!...

[F Peeters (MythTV)]

When I run live tv with XvMC, the log shows:

VideoOutputXv: XvMCTex: Init Failed
VideoOutputXv: XvMC Adapter Name: 'NV17 Video Texture'
 X Error: BadMatch (invalid parameter attributes) 8
NVP: Prebuffering pause
NVP: Prebuffering pause
NVP: Prebuffering pause
NVP: Prebuffering pause
NVP: Prebuffering pause
NVP: Prebuffering pause
etc.

Audio is perfect, but image sometimes stutters visibly on big screen changes

When I use libmpeg, the sound is a bit rough, but video seems to be smooth...

OpenGL VSync is disabled (turning it on freezes the frontend machine solid)

Both backend and frontend run on this machine. I am using 0.20 from
Marillat on Ubuntu Edgy Eft
