What's more troubling is the the mount command complains about attempting to mount 'read and write' while clearly the fstab entry is 'ro'. That means that when you attempt to mount the CD the above entry is not read. I am not sure where this is coming from. I noticed that you have NFSv4 running so that might be the source of the problem somehow? Because you can give the identical command from a terminal mount /dev/cdrom /mnt/cdrom -t udf,iso9660 -o ro,noauto,owner,kudzu after you insert a valid CD in the drive and it should work as you said. That mean that /etc/fstab is not read properly or is diverted somehow to somewhere else? I am not sure...
