I am using DVD Studio Pro 3 - on a G5 - running 10.3.9.
I cut a 21 minute movie in FCP 4.5. Used Compressor for export, 60 min. High Quality preset.
Brought the Mpeg2 into DVD Studio and burned a DVD. Upon inspection of the disc I noticed a shot the client ask to be cut was still in the movie. I cut the shot out - re-did everything I did before. When I went to burn another DVD I received an error - Video Bitrate Too High. The bitrate average is just below 6.5.
I've tried this a couple of times. Even tried the old "regenerate power" trick - same message.
Also check whether you accidentally changed the quality setting when you re-generated the file. I once received the same error when I re-generated an AVI at a setting of "Thousands of Colors" instead of the original setting of "Millions of Colors"
