I have a VCD compliant file ( will burn in full OK ) but when I try to split it using MPEG tools in TMPGEnc it lose's the audio ?

If you split the audio from the stream and look at it in wavelab it is 0db of silence ?? ( in other words there is a wav componant but it is at zero level ).

I am also getting this with a full 780MB avi file, it plays ok on its own through media player etc, but when I split it in TMPGEnc during encoding I get the same issues.


What is the stupid thing I am missing out on here ?
