Vision Express 3 - background with no audio

I have been doing a couple of dvd's of fave tv progs with windows and an animated backgorund. The first one did have sound, the subsequent two didn't. Anyone have a clue whats happpened ?
Also - how can I direct the 4.3gb away from the C:\blahblahblah\temp folder and into another ? Nero doesnt delete after burning. I thought it did that automatically. I have to use the excellent "wash 'n go" prog to get that folder (whiich I cant find) empty to provide space. EVERY time.

 

What are the formats of the original dvds (e.g. aiv, mpeg)?

 

.avi

But it's worked fine before. Something must have been altered somewhere, but where ?

 

You may use e.g. Gspot or Shelock to check whether the codecs have been corrupted. Or you may use another converting program (e.g. VSO DivxToDVD) to see if things are better.
