Everytime I come to burn a disk it says "Media incompatible". I use .AVI files.
MyDVD is rather old and it's possible that it doesn't understand new burning techniques or file formats, even if you use AVI files. Try to use Ashampoo Burning Studio and you should overcome this error. However, the error could be caused by the fact that you are trying to create a Video disc and the system lacks the proper codecs. Install CCCP Codecs and then try again.
