If you are talking about burning an avi or mpg file onto disc as a dvd image (ie so that it can be played on a dvd player) then of course it will take so long, especially if your pc's a couple years old.. . Nero has to convert the file to the correct DVD format (which is what takes the time) THEN burn to the disc, which itself should take no more than 10 minutes (unless you have an old, slow DVD burner).. . It all comes down to how fast each component is. If you have a slow CPU and not so much ram, then it'll take ages to connvert the file. If you have a slow DVD burner, then it'll take longer to burn.
