If you're trying to get a particular stream, ffmpeg2theora will print
a list of all the streams when starting encoding, along with their
languages, if known.
It's possible that ffmpeg2theora was compiled without support for
the codec used, too.
About subtitles, ffmpeg2theora only supports text ones, but DVD
subtitles are in image form.

If you're on Linux, I'd suggest something like Thoggen, which will
let you choose a particular audio track from a menu, and will
handle multiple VOB files.
