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:
 http://www.bigbuckbunny.org/index.php/download/

 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
 }}}

 {{{
 $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
 ondemand
 $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
 1000000
