[Openchrome-users] Poor video performance on EK8000EG

[stubie]

Re: Poor video performance on EK8000EG
Thanks for the help lads.

After reading an earlier post ('video play problem') I realised I could get the chipset using:

dmesg | grep -e agp -e drm

Also looks like the openchrome version is: 0.2.6+svn357-0ubuntu3

I restart the PC and for some reason the video playback seemed fine (using xine 1st then mplayer), even h264 was playing fine. Although after a while of repeated playing they showed the same symptoms - stuttering (caused by low frame rate I guess?)

I have attached my xorg.conf and xorg.log as requested.

Thanks again.
