Toast will import the MPEG2 file, but does not see the audio file as linked to the video. Importing Quicktime directly to Toast negates the need to go to Compressor. It looks as if choosing the DVD option in Toast creates a final DVD with or without menu. You can also choose the quality level as well. The reference Quicktime movie should work, but you might want to export a two-minute segment from your project as a test. I don’t know how long Toast takes to encode and then write the files to DVD.
