Does anyone know why when i copy a film with neodvd plus to dvd the film is fine but there is no sound whatsoever on any dvd players not just on computer.I convert the file from a avi to a mpeg first and the sound is fine on that but soon as i burn it with neodvd plus the film just has no sound???? any ideas??

The only 2 films where i did get sound were cannibal ferox and cannibal holocaust probably because they are older films and the sound is basic i guess but any newish films no sound everytime
