First of all, your G200 *is* up to the task, but only if you run it in
1024x768. That resolution is better than any DVD anyway.
Secondly, the limitation IS your video card's memory bandwidth. The Xv
system can put a lot of stress on that video RAM bus. It is possible to
not have that banding by putting more of the load on your main CPU.
Simply use "xine -s".
