Missing Audio!

[newsgrant]

I'm new to dvd shrink...

I have ripped a title from a dvd (it's a personal dvd, no copyright or anything) but the audio is missing.

I tried a couple of other dvds and the audio extracts on some of them, but not on others.

Please advise asap. Thanks.

What did you originally make the DVD in?
