Comment (by ignissport@…):
I've experienced this when playing Big Buck Bunny in h.264 @ 1080p (plus
any other 1080 content)
The file is large (700mb for 10 minutes of video), but it's readily
available:

I'm in the same boat. VDPAU, plays with very low CPU utilisation (~7%,
loadavg: 0.6 - 0.9; sometimes exceeds 1.0) and stutters. Played fine under
0.23-fixes. SD content (<= 576p) has always played fine.
Also get jitter on MPEG-2 1080i DVB-PAL content. Mine also jitters
immediately. No 20 sec delay.
Basic setup:
{{{
Athlon X2 4200+
NVidia G210
Mythbuntu 10.10 (Maverick)
+ ubuntu-x-swat/x-updates ppa
+ mythbuntu/0.24 ppa
+ medibuntu ppa
