Googling for this error turned up this, hopefully it'll help:

This is probably related to your DVD issues also affecting lsdvd and dvdinfo.

dvd://<title> is mplayer/mencoder's syntax for accessing DVDs. Some
more information on the complete syntax is available here:

VOB files are just containers. You don't need to deal with them
directly. Background info available here:

Possibly. This'd introduce a dependency on lsdvd to find the largest
title, but it's certainly doable. I'll add it to the TODO list.

Personally, I use the DVD ripping less than I use it for re-encoding
videos I've already got. I think the best way, TBH, would be to allow
a syntax like:

    tablet-encode dvd:// myfilm.avi
or tablet-encode /media/cdrom0 myfilm.avi
or tablet-encode /dev/dvd myfilm.avi

...and have it a) detect it as a DVD, b) call lsdvd to find the
longest track and generate an appropriate URL of the form
