It could be.  Check the rights of the device, and mount locations.  Long shot 
but hey, you never know.

What app are you using to watch them?  (oh, check hdparm settings to see if 
dma is on, should be by default I think, but its worth a shot too.  to do 
this enter "hdparm /dev/hdc" without the quotes, if your dvd/cd is the first 
device on the second IDE channel).  Along the hdparm thing, I have seen some 
IDE drives actually slow down when you turn on 32bit IO support so you might 
try turning that off (hdparm -c 0 /dev/hdc)

In Mplayer under preferences check double buffering, etc. in the video 
preferences tab.  (you would think this would only affect video output, 
but . . )
Also the Cache settings are under the "Misc" tab under preferences. for 
Mplayer.

For Xine:  You have to set the configuration experience level to Advanced 
under "gui" to see the cache settings (I think) which are on the Media tab, 
look for read ahead caching and make sure its enabled.  
Hope this helps.

I'm running Dapper, and have watched a couple of DVDs, which means if you hang 
in there its possible.  It just might not be right now. :-D
