Sound problem -> no sound in ripped file

[spiritcrow]

I am just starting with ripping DVDs, actually just had my first try and already running into problems despite reading all the tutorials I could find.
I tried to encode ONE part of the Buffy Season 2 dvd (UK version), an interview clip, with SmartRipper and CladMdec . Works just fine, the resulting vob files have a good picure quality and everything but NO sound! Tried decoding it to avi (with DVD2avi) and it doesn't even produce a seperat wav file like it should so there doesn't even seem to be an audio stream.
I am a newbie to all this, but think I did everything right anyway - maybe I am missing some codec or doing something wrong afterall? Could the ripping of just that ONE part of the VCD be the problem?
Would be great if someone could help me
Oh if anyone needs that info - running on a Pentium 4, win xp home edition.

you dont save as a AVI you saveit a a project and remember to select a track number on the audio

uhm, I dont even GET as far as converting it to avi - the resulting vob filea after using smartripper are the ones that don't have sound.

how do you know they have no sound? just playing them in mediaplayer etc... is meaningless

Played them in Power DVD - even followed the advice to use VobRator to change the Audio Track from x84 to x80 for PowerDVD and whatever converting tool to recognize it as the main audio track. THAT worked for all "files" but one.
I found a way around it though, probably silly, but it worked. tried to extract the audio seperatly with Vob2audio but even THAT gave me an error message (by now I think something is technically wrong with that one file). So I simply recorded the audio with Totalrecorder while playing back the DVD and put it together with Tmpg Takes a bit of fiddling around til its in sync, but it worked and I am happy with the result.
Still, can it be that that one part of the dvd is really corrupted in terms of audio?
