Are you reproducing a DVD, or are you trying to _watch_ a DVD? your
description sounds like the latter (reproducing a DVD implies copying).

Check out hdparm and using it to turn on DMA on your DVD drive. Your
computer is new enough that it's almost certainly capable of DMA, and a
simple instruction like 'hdparm -d /dev/dvdrom' (or whatever your device
is mapped as) in your boot scripts will make a world of difference.
