Hi Group. I've just built up my Shuttle PC with built-in S3 UniChrome card. The video playback performance for DVB and DVD are REALLY poor. Lots of skipping and staggered picture. I have got a few (smaller res) avi's of Star Trek episodes that play ok, but the DVB/DVD is to bad to watch with either MPlayer or Xine. When I run 'xine-check' I get : Please be patient, this script may take a while to run... [ good ] you're using Linux, doing specific tests [ good ] looks like you have a /proc filesystem mounted. [ good ] You seem to have a reasonable kernel version (2.6.11.7) [ good ] intel compatible processor, checking MTRR support [ good ] you have MTRR support and there are some ranges set. [ good ] found the player at /usr/local/bin/xine [ good ] /usr/local/bin/xine is in your PATH [ good ] found /usr/local/bin/xine-config in your PATH [ good ] plugin directory /usr/local/lib/xine/plugins/1.0.1 exists. [ good ] found input plugins [ good ] found demux plugins [ good ] found decoder plugins [ good ] found video_out plugins [ good ] found audio_out plugins [ good ] skin directory /usr/local/share/xine/skins exists. [ good ] found logo in /usr/local/share/xine/skins [ good ] I even found some skins. [ good ] /dev/cdrom points to /dev/hdc [ good ] /dev/dvd points to /dev/hdc [ good ] DMA is enabled for your DVD drive [ hint ] Your X server doesn't support YV12 overlays. That means xine will have to do color space transformation and scaling in software, which is quite CPU intensive. Maybe upgrading your X server will help here. If you have an ATI card, you'll find accelerated X servers on http://www.linuxvideo.org/gatos/ press <enter> to continue... [ hint ] Your X server doesn't have any XVideo support... XVideo is an X server extension introduced by XFree86 4.x. This extension provides access to hardware accelerated color space conversion and scaling, which gives a great performance boost. If you have a fast (>1GHz) machine, you may be able to watch all kinds of video, anyway. You will waste lots of CPU cycles, though... press <enter> to continue... any ideas? Simon
