[mythtvnz] DVD not mounting

[James Booth]

Hi All,

My Mythbuntu box has suddenly started refusing to mount my DVD player 
(actually a Lite-On Blu-Ray/DVD combo drive). The drive works fine, as I can 
boot from it, but on a normal boot it simply refuses to work - I get the 
message that "Special device scd0 does not exist" if I try to manually mount 
(and indeed, it does not). I have searched and it appears to have been an 
issue for a lot of people using Ubuntu, but I have not been able to find any 
definitive fix. I know this is not specifically MythTV related, but there 
seem to be plenty of knowledgeable people on this list, so I'm hoping someone 
can help.

I have not applied any updates etc recently - it just suddenly started 
misbehaving.

Any thoughts would be appreciated. Here's my fstab, for what it's worth:
