[mdlug] Unable to mount a dvd on a drive which was used to write it.

[Jeff Hanson]

Sounds like a permissions problem with the mounting system.  Which distro?


The medium error could be resolved by reducing drive speed with hdparm but
I'm not sure if that is the cause of your problem or a symptom.

You could also try mounting it as the user with pmount and manually specify
the filesystem:
pmount -r -t iso9660 /dev/sr0 cdrom

To umount it:
pumount /dev/sr0
