Back to the Future 1 audio problem

[sreg0r]

Hi, i have been trying to backup a copy of BTTF Trilogy 1/3 but am having problem with the audio not working. In the original DVD once the movie is playing you can't select alternate audio streams and it appears as if there is only one. But if you select directors commentary from the bonus menu then play the movie the audio is directors commentary but still there are no other audio channels listed in the audio menu of powerDVD. Now when i strip the DTS track with ifoedit this doesn't work anymore. I assume this is because the DTS was track 2 and now the directors commentary is track3 and it's not pointing properly. Has anyone ripped this movie and can give me some advice? i can post the .ifo files if that would be of any use.
thanks Alex.

Not sure about what method you use but I know everything will work right if you use DVDShrink. It's not a problem with the movie.

thx but i don't use DVD Shrink. I will only ever use DVD-Rebuilder. The only thing i've done is stripped the DTS audio, which effectively removes all references to the stream and then the directors commentary is moved up to channel 2. But i guess if if you can't select audio channel from within the movie i could just delete the DTS stream in Rebuilder and leave it referenced and remove the DTS buttons with menuedit.
Thanks i guess i just solved my own problem.
