I'm not sure what you've done here... a DVD is the disc the relevant
files are all those in the video_ts subdir.

If you made an image copy of the DVD (i.e. cp /dev/dvd spiderman.img)
the just point libdvdread at that.
If you used some 'ripping' tool, I sugest you ask the author of that.
I'd guess it just 'copied out the parts of several VOB files that made
up the title and concatenated them, if so it's basicly just a MPEG2
sytems stream, with some DVD specific blocks mixed in. Though nothing
that would tell you the total playback time in an easy way.
