I don't know what to do I feel like I have been cheated. I bought this program months ago and when I finally go to use it to burn dvd's all my files say the same thing except two. The two are the same format as everything else I been trying. One file is .mp4 and the other is .avi. Occasionally it will give me a message for files about the audio format being ac3 but other than that nothing. Is there something I can do. All help is greatly appreciated!
