I am helping a friend who has the same card (PCI). It stutters using
XvMC for 1080i when playing through myth. Whats odd, is that when we
play the same video through xine or mplayer using XvMC it works
perfectly.

Unless myth is using a higher color-depth or something funny like that,
I can't see why it would need more PCI bandwidth than xine or mplayer...

Any thoughts? (we have recompiled myth several times, but havent tried
the latest svn).

Thanks
