Hi! Just bought a brand new tv, with native 24p (120hz) and of course 1080p.
When I came home I Immediately booted my htpc (xbmc nativly using archlinux kernel) and to my suprise for the first time i'm having a few issues with the movie playback.
My issues using 24p/hz:
htpc
archlinux (2.6.36-ARCH)
Amd Athlon 64 X2 Dual Core 5000+
Nvidia 9500GT 512mb
2GB Ram
Most of the playback would be from hardware acceleration through my GPU right, vdpau? I've seen setups with far less cpu power and they've had no issues, granted it was mediaportal and on windows. But clearly my CPU isn't a bottleneck here, right?
xorg.conf
xbmc version: 35648-1 (svn)
xbmc log: http://paste.pocoo.org/show/311646/
xbmc settings:
My movies are buffered from my server (all wired on movies, no wireless) - htpc, server is running linux with a 1GB switch and linksys router (tomato), they are all 1080p, mkv x264.
I'm right now watching Gladiator Extended Cut 1080p (2010 remastered version), and I have over 4000 frames dropped within the last 10 minutes. If I press "O" the frames are dropping like seconds, i'm soon past 4500.
UPDATE: The Audio is now falling behind roughly 2 seconds (even when i'm using audio offset 250ms) and the frames are dropping like flies!
I've searched this forum, used google and read a few guides and tutorials. Alas my problem isn't solved and since it's related to a general playback of my system, this is a fairly large issues for me.
I humbly ask for help

My issues using 24p/hz:
- Tearing (nvidia-vsync enabled)
- Audio out of sync (have to set audioff set to roughly 250ms)
- stuttering, picture almost goes into slowmotion for a split second, happens throughout the movie
- framedrops constantly
