[mythtv-users] Intel video

I have an Abit iL-90MV motherboard which is a very cool MOTD board with 
integrated HDMI. I am very impressed with it; I just connected to the 
Plasma and got 1280x720 video and sound with barely any configuration! 
However I have found that when playing back video (MythTV and xine) I 
get a corruption line that gradually moves down the screen. Kind of 
reminds me of tracking on a VCR! I've tried various different MythTV 
options like XVMC and they all either have the same problem or very 
jerky video instead.

Does anyone have any ideas how to solve this please or has this been 
seen before? I really don't want to have to get a new graphics card; 
this machine was supposed to be low power and I've never seen such good 
'plug and play' with Linux displays before!

I upgraded X11 from 7.2 to 7.3 and xf86-video-i810 from 2.1.1 to 2.3.2 
yesterday but that made no difference. It runs Gentoo with the following 
various software:
x11-libs/libdrm-2.3.0, x11-base/x11-drm-20071019, media-libs/mesa-7.0.3, 
x11-base/xorg-server-1.4.2, x11-drivers/xf86-video-i810-2.3.2 and 
x11-base/xorg-x11-7.3.

Various other info below.

Cheers,
Dave.
