Does anyone have an idea why cpu usage varies constantly, from as low as 4.X % to as high as 20+%? All that I have open at the time of running "top" is the gnome-terminal. The reason why I'm hunting this, is that I just can't seem to play DVD's (using Xine) without choppy playback (sound is fine). I know my laptop is aching - running CentOS 4.4 with a Celeron 800 and 256MB RAM (DMA's turned on), but still - I think it should be able to play DVD's, or not? I have the feeling that the more I can tweak CPU usage, the better my chance of success will be. Any advice would be appreciated.

You are wrong. You have plenty of other things running as well, including Gnome, which is a heavy beast.

If you are planning on playing DVDs and other such stuff on your laptop, I suggest replacing Gnome for some more lightweight window manager. My personal recomendation is IceWM, but there are plenty of others. Gnome and KDE are not recomended (by me) on anything with less than 512MB RAM.

DVD Sounds to me like DMA. Which xine are you using? Have you run xine-check? Are you using SATA?

I had a similar problem setting up xine for use with MythTV. The solution was to make sure you have proper drivers for your video card installed and then run xine with the correct "-V" parameter to make use of those drivers. Running "xine --help" will give you a list of drivers available.
Specifically in my case I am running X on a Hauppauge PVR-350. I had to compile and install the X-driver for the IVTV module driving the Hauppauge (which was achieved after the death of thousands :)) and then run xine with "-V xv". I've been happily watching DVDs sans-chop since then.
Hope this helps.
