Hi, I just downloaded a movie and its MP4. What do I need to add to my WinAvi Converter so I can make this movie into a Dvd? I have ben converting avi's to dvd formats just find but I can't even play this movie on Windows Media Player or Real Player. Do I need a certain codec and what would it be? I am wanting to contert it to dvd format to burn on dvd. By the way, the movie is called "Bee Movie" if that matters. Many thanks in advance.
