i know this was just posted up but... it really sounds like the dvd isn't running in DMA mode. i had this problem on my thinkpad at first, dvd would be choppy as you suggest, music i played would also be. fixed it by enabling DMA on the drives - in my case it was actually using the wrong kernel module for the drives.
check the output of dmesg (as suggested by another) or the output of hdparm -I hope this helps.
