i recently bought the program Toast, and I have 2 .avi files, and when I tried to burn them using the DVD video option I can see it fine on my DVD player, but there is no sound. Am I doing something wrong or do you think the files are messed up? Is there a way to merge the two files to make it one file, or should I usually be able to drag as many files as I want in Toast to one DVD? Any help would be appreciated, thanks.
