cutting divx in two - suddenly there's no audio :-(

[Superully]

hi, i'm new ti this kind of stuff, so please don't mind my asking:
i've got a divx-file of about 750 megs and want to convert it to svcd. however, the file would be too big then to burn as an svcd, so i'll have to split the avi-file up in two seperate files first.
as someone suggested here i use TMPGEnc to do this. using the wizard i choose what kind of format i'd like to create (in my case svcd) and then load the avi-file. in the following menu i select "source range" to mark the position where i'd like to split the file in two. now comes the problem: outside of TMPGEnc the avi-file plays perfectly - audio and video are just great, but when i open the file with TMPGENC and want to cut it in "source range" i get NO AUDIO SIGNAL - just a flat line. but this is no error, continuing with the conversion only leaves me with the picture, no audio at all. where did it go? am i missing a codec of some kind? can someone PLEASE help me out here?
once again the problem in short: a file with perfect audio is shown as a file WITHOUT audio in TMPGEnc

You could cut the movie in two with VirtualDub and then encode the two parts with TMpegEnc.

Use the source range setting as before, but first save out the audio as uncompressed .wav (full processing mode).

saving out the audio as an umcompressed wav-file (what do you mean by "full processing?) doesn't work either - still NOTHING to be heard. once again: the funny thing is that audio works perfectly when playing the avi-file on my PC!

Selecting Audio>Full processing mode is what you do to save the audio as uncompressed wav. The only time this won't work is if you don't have mp3 audio.
