Not sure if this is the appropriate place for this, but I don't know where else to go.

I did a stupid thing...

I was backing up some files to DVD-RW using Nero and my Pioneer DVR-A04. Nero gave me a message about "This compilation doesn't comply to ISO-9660 because you have folders more than 8 levels deep and total paths of more than 255 characters" (something along those lines)

I burned the disc anyway, and then forgot that there had been any error messages, assumed the backup was good without testing the disc, and erased the orginals from my HD.

Now XP won't read the disc, and I'm stressed that my backups are permanently hosed...

Is there any program or filesystem driver or something that'll allow me to get my files off of this non-compliant DVD-RW?

Please help!
