Yes I found the same problem. Never did find out why, but for me I found a solution.

Any movie that reported an excedance of a 4.7 gig DVD I resolved by using the initial editng screen in TMpeg following the identification of the file screen.

I would preveiw the movie for a few frames and then set the start movie tag. Then I go to the end of the movie and rewind a few frames and then set the end marker. When I then go to the last screen or template before file save and encode I find that it now reports a much smaller file.

I assumed this meant that something was wrong with the reported "header" flags, but it was not important to find out what since the fix worked, at least for me.
