OK, so first of all I'd like to admit that I'm a completely new Mac user. I'm having some problems with burning avi's to DVD. I have all the codecs and the files play in Quicktime. I'm trying to burn them using iDVD and all the previews work just fine, it burns easily, but then when I stick the finished DVD back into the drive on my Macbook the video just comes up as a blank green screen. Am I doing something wrong or should I perhaps try using Toast or something?
