ASRock 330HT 1080p playback jitter during panning or action scenes

The video i am playing back is 1920x1040, encoded in x264, xbmc is using vdpau to decode the content. Scenes that include action or panning cause jitter/tearing in the display .

Looking for some advice on how to track this down..

Some environment specific details.

TV :
Sony Bravia 55inch LCD

OS :
Ubuntu Karmic running XBMC 9.11
Nvidia-glx drivers v195

xorg.conf details:

HorizSync 15 - 70
VertRefresh 58 - 62
ModeLine "1920x1080" 74.18 1920 2008 2052 2200 1080 1084 1094 1124 +hsync +vsync Interlace

Your refresh rate should be set to 23 or 24Hz when playing this content. Your current output seems to be set to 60Hz, which means some frames need to be skipped.

Be aware that the Bravia won't accept 23 (or 24)Hz through VGA, only through HDMI.

Turn on vsync in xbmc and disable the composite extension in xorg.conf.

thanks, it seems removing the composite setting has solved the issue ;-)

for others, simply adding the following to /etc/X11/xorg.conf did the trick..

Code:

Section "Extensions"
        Option  "Composite" "Disable"
EndSection
