Does anyone know why when I try to burn a movie i downloaded from the internet I get no sound??? I mean it works i get a perfect picture but no sound, when i preview it before i start the burn there is sound it works and looks great. The finish product however has no sound at all.....I have looked this up in other forums and it seems that I am not the only one this is happening to yet not one person has a answer for why it is happening....is there a way I can reinstall windows dvd maker or is there a better simpler program i can install that is free to use for windows 7 that can burn dvds. I dont want it to be to complicated and i dont want to pay for it. Is there anything like that out there that works well with 7????
