What did you change in between the times when you could mount it and when
you couldn't? Every detail you can remember is important.

Can you post the full listing of the device node?

Hmm, why did you use /dev/sr0? Is /dev/dvd a link pointing to it? If it
is, then please post the full listing of /dev/sr0. If it's not, indicate
why you think /dev/sr0 is the proper device node.
The error "No medium found" means mount thinks the drive is correct, but
there's no readable disk in it. What disk are you trying to mount? Don't
try to mount a music CD. Make sure whatever disk you're using is valid, or
else you'll never get this error to disappear. Do you have a known good
data disk you can try?

Oh, yeah, what kernel are you running? Are you running devfs, or udev?
