I've recently made my first DVD using DVD Studio Pro v 2. I used compressor to export the footage from FCP and got both sound and video files fine. However, when I import these into DVD Studio Pro, there is no sound. I then tried from Cleaner and had the same problem. In the end I had to use the FCP Mpeg 2 codec because when I tried
DVD studio pro's own, the file size was too big. It was a two hour video and I had to make two DVDs. Couldn't get anything to compress it to one DVD.
