How to transform VOB files to AVI - Audio issue

[Skyfish]

OK this is a real noob question but I have been reading all afternoon here to try to solve my problem and I still fail :(

I am using DGindex and DGrecode to have all my vob files into VirtualDub-MPEG2 with a .avs script.
So far no problem with the recently released version of Neuron2.
I use NicAudio.dll for the ac3file (since this is what I get with DGindex)
However I end up with a huge .ac3 file and when I try to merge both video and audio (the .d2v file is 700kb and the ac3 file is 200MB) I end up with a huge .avi
I have tried in VirtualDub to also use "full processing mode" with MP3 compression but I then get a message the sampling rate and number of channels is not compatible with the selected audio compression format.
Do I need to use yet another application to treat the ac3 file before I can mux it in virtualdub again ?
Am I doing things wrong in VirtualDub or DGindex ?
HELP !

Here is a copy of my .avs :
LoadPlugin("C:\Documents and Settings\Skyfish\Bureaublad\dgmpgdec150b7\DGDecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\NicAudio.dll")
video=MPEG2Source("Madagascar.d2v")
audio=NicAC3Source("Madagascar.ac3") --used to be named ...DELAY 0ms
AudioDub(video,audio)


HELP !

Use something like BeSweet to transcode the ac3 to mp3.

Thanks for the tip !
Now I have to find an MP3 filter for AVISynth though... I will google it.
In the mean time : any link/advice is welcome :)

Skyfish, no, just encode video separately (kill the audio part in avisynth), and after that mux the mp3 with this new encode.

OK will try thanks

I feel very stupid but how do I get my AVS script to work without audio now ?
I need the AVS script to assemble the different VOBs in VirtualDub but I can not make it work without the audio now :(

LoadPlugin("C:\Documents and Settings\Skyfish\Bureaublad\dgmpgdec150b7\DGDecode.dll")
video=MPEG2Source("my.d2v")
return(video)

Thanks a lot for this :)
Will try asap

Creating 1 large avi (with xvid compression) from the different VOBs went perfect with the srcipt in vdub : thanks !

I used Vdub in (video) Direct Stream copy to Mux the MP3, I hope this the proper way to do this.

So to transform VOBs I have on my hard drive into single compressed avis with no menus or titles, I have to go through all these steps ?
Isn't there a simpler/faster way to do this ?

Yes. You can always use Vdub's job queue.
