I did notice some odd behavior as to which device worked. It seemed to
allow hd? devices a couple times and then not others. I ended up
checking my /var/log/messages (I think dmesg had the info also) for
which device the dvd drive was bound to... hang on let me grab it...

Hmm, so, I ended up using /dev/sr0 in some cases also.
It is important that the sr driver load. So even if you don't have to
use the sr device, make sure that the above line loads to an sr? type
device. I forgot that sr? was important...

When the dvd is burned ok you won't need to specify fs type, as it will
be correctly auto detected...
