writing on CD-R

[toyfactory]

I've managed to write to CD and DVD no problem.  The entry in my fstab
reads: /dev/sr0 /mnt/dvdrw udf,iso9660 ro,user,noauto 0 0  I'm guessing
that growisofs (which Nautilus seems to use) doesn't use the fstab
entries.  Have you tried reverting to the old fstab and mounting again?

This is just a guess, you might want to wait for some more "expert"
advice, as I don't really know what I'm talking about!

Cheers,

Nick
