[theora] vob file with lots of subtitles.

[Jesus Sanchez]

Hi there, first mail to this list, I hope to not disturb with my
question.

I'm trying to encode a VOB file (from a DVD) with ffmpeg2theora, but it
have a lot of subtitles (about 26) and I can't find the correct
--audiostream id to encode the file in my language. I have tried with
ids from 20 to 40 and so on and all times the audio kbps it's 0. mplayer
and VLC can play the .vob file without problem and also let me choose
the audiostream.

Any suggerence?
