You probably don't have DMA activated.

I have my DVD on /dev/hdc, and I do this as root:

hdparm -d1 /dev/hdc

Then, if this works, you can put a script on /etc/init.d and a link to it in 
/etc/rcS.d, so DMA gets activated during boot-up.... however I am not very 
sure about this last step, I've never done it in debian (only in SuSE), so 
maybe one of the more learned debianites can tell us about it.
