Have you checked top to see if it's a CPU, RAM, or IO (disk access) issue?
The wa% is very useful sometimes as it can show you there is a hang up with
your DVD drive.

Do you play DVDs from disk or ISO?  Have you tried to rip the DVD to ISO and
play the ISO back to see if it's your DVD player?  Do you mount ISO's over a
network drive and play those, in which case it could be a bandwidth issue?
