ok, I have an avi file on my macbook and I have all of the codecs, meaning it plays fine in quicktime. I used toast 8 to burn this file to dvd but when i put the dvd in the dvd player, it doesnt play, theres just a black screen. i tried idvd but im having issues with that too.... there is no sound. please help, i do not want to waste all of my blank dvds. I just need to know how to put a saved movie on my computer on a dvd to play in any dvd player. Thanks
