Excellent, some positive progress:

$ file -s /dev/hdc
/dev/hdc: ISO 9660 CD-ROM filesystem data '2009_12_06_05H00M_PM'

Yet the filesystem structure is not innately recognized, nor is it
explicitly:

# mount -t iso9660 /dev/hdc /mnt/dvd
mount: Not a directory

dvdrip -> "Rip Title" -> "Read DVD table of contents" (dev/hdc default)
produces no dvd activity, no results, and the 3 GUI buttons remain greyed
after the selection, although the "Logging" tab displays:

"... mounting it as UDF" doesn't work for file access of any kind, as it
simply doesn't mount.

$ lsdvd /dev/hdc
Can't open disc /dev/hdc!

Something strange on the DVD for sure, although it can be played in a
regular hardware player..

/mnt/dvd has to be an existing directory.
What does "ls -l /mnt/dvd" tell you?

Hmm. libmozjs.so? That sounds suspiciously like it's being treated as a
library private to certain browsers and mail clients.

gxine should be requiring libmozjs.so.2d (these days), and that should be in
the default library search path. If not, then your libmozjs or xulrunner
installation (whichever package provides libmozjs.so) is broken and you
should probably be filing bug reports in the appropriate place (and working
around this brokenness by setting LD_LIBRARY_PATH appropriately).

(Surely Debian aren't the only ones getting this sort of thing *right*...)

Ouch. But I see from another posting that it's apparently an ISO9660 FS, yet
not mountable...

I can't argue with that. I suggest complaining loudly at whoever provided you
with that DVD.
