Wow - you are cutting ads? What do you use? I found it exceedingly 
different to cut ads without losing a/v sync when doing that before 
reencoding (although I finally found a tool).

After reencoding you get a completely new file structure with newly 
placed time codes. I am not sure you that would relate to the demuxer 
but, hey, everything is worth a try.

As for the output avi and VLC's error message - multiplex the thing into 
matroska from the avi (you can just feed the whole avi into the 
multiplexer without additional parameters) and play that (or output into 
matroska to start with using the mencoder matroska multiplexer).
