I have a .avi file and I would like to convert it to a format to watch it on a DVD player. I have the roxio titanium software but each time I drag the .avi file into the software it says 'it was not added because a required codec is missing'. I was wondering how to fix this problem. Or if anyone else has another better software I can use. All the forums I have seen say all types of things that haven't seemed to correct this problem. Any help would be greatly appreciated!!
