I have 15 .avi files that I have successfully converted only 13 of to a file that DVD Author can utilize. I used Virtual Dub to separate the .wav file associated with the .avi. I used DIVXtoDVD to make the .vob and associated files. When I try to use Author to pull them together I get the following error: "Could not initialize decoder." I have tried deleting and downloading the .avi files to no avail. HELP!!!!
