Playing dvds in Linux isn't strictly legal, you need to use a ccs
descrambler which means you need a plugin for xine, altough ogle comes
with one built in if I remember correctly.

To change the DMA modes or to turn DMA on for a device look at the man
page for hdparm, read it and make sure you understand it because it
could cause damage if used incorrectly (disclaimer). 

As an example I use 'hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda' to enable
udma 66 on my hard drive.

Another useful command is 'hdparm -t /dev/hda' this will do a test on
you disk to see how fast it is transfering data and gives output like
this:

/dev/hda:
 Timing buffered disk reads:  64 MB in  2.34 seconds = 27.35 MB/sec
