Xine Playback Choppy

[Todd Johnson <todd toddejohnson net>]

I have an Inspiron 6000 with fedora core 3 kernel 2.6.10-1.770_FC3.  I 
have researched playing dvd's with xine and i ran the xine testing app.  
It tells me that dma is disabled.  I cannot re-enable dma.  I posted to 
the dell forums about problems playing dvd's.  A SuSE guy replied and 
said the latest kernel changed the pata drive from /dev/hdc to 
/dev/sdc0.  At notebookforums they say they "unblacklisted CD/DVDs from 
the libsata code."  I was hoping for a way to fix this problem. Any help 
or ideas appreciated.
