This is from the xine FAQ. The FAQ for a program/project should always
be your first port of call

<quote>
Set up and use raw devices for dvd access. Please note that this is
usually not worth the effort as the performance gain from it is very
small if any. 

Raw devices should be available in linux kernel 2.4.x and there are
patches for older kernels available from:
ftp://ftp.kernel.org/pub/linux/kernel/people/sct/raw-io/ 

To use raw devices, first connect a free raw device to your dvd device,
use something like: 
  	      raw /dev/raw1 /dev/hdc
	    

then create a link named "rdvd" pointing to that raw device: 
  	      ln -s /dev/raw1 /dev/rdvd

(Note: Slightly edited, since the faq has a typo on the last line above)

Note the first line, it's usually not worth the bother. I don't use raw
devices, and I get very good performance from xine
