I successfully made a movie and printed it to tape.  I then went back about a week later and decided to make a "making of" segment.  I put that on the timeline next to the previously rendered movie. I had also made some corrections to the part of the movie that I had printed to tape.  When I try to print the entire affair to tape again I got an error message: an error occurred while trying to create the media file.  Error 0x8007001f(message missing) any thoughts on how I can rescue this movie?
