I tried using vob2audio but it keeps giving me an error.(Dont reamber the error but its the same one eevryone gets, something about a filter)

So ive been using Graphedit using this guide: http://www.doom9.org/graphedit_wav.htm Sometimes when I do the first step, render media, it will play another track(Ie-The wrong lanuage) How do I find out what track I need to select???????

And before you ask why I dont rip the audio w/ dvd2avi its cause using graphedit gives me a better,louder sounding playback.

Thanx
