As far as I understand it...

...libdvdread supports both direct device access (when you pass it a block
device or a regular file - character device is missing here, too) or 
regular file accesses (when you pass it a directory which should be the 
mountpoint of a mounted DVD-ROM disk).  See dvdread/dvd_reader.c, function
DVDOpen().

No.  Should work on Linux, too. 

I'm not sitting in front of a linux box now, but the following should work:

	mount /media/dvd
	.../libdvdread-0.8.0/src/title_info /media/dvd
