I've read many of the posts below describing issues with DMF4. Luckily, my experience so far has been pleasantly bug free. In fact, I am perplexed at how DMF4 is able to accomplish what it does so quickly.
To explain my question, I have imported into DMF4 some MPEG2 files that I recorded with my DVD camcorder (Sony DCR-DVD403). As an experiment, I first burnt a DVD without editing the files at all. The disc creation and burn process was very fast as expected since DMF4 did not have to do any rendering.
Then, I redid the DVD after splitting some of the files and adding transitions, some music and some text. I had been expecting to wait for hours while DMF4 re-rendered the video. To my surprise, however, the disc creation and burn was almost as fast as when I just burned the MPEGs without editing. Does anyone know how DMF4 accomplishes this? Is it selectively re-rendering just the effected portions of the video?
As a comparison, performing the same editing with Womble first took about six minutes per clip, which, given that I had several clips, would have added many dozens of minutes to the DVD creation process.
How does DMF4 do it? What am I missing here?
How does DMF4 work so fast?

MF4 is performing "Smart-rendering" and as you said is only rendering
the affected portion of the video.
For MF4 to do this properly the "Project Properties" should match the
video source properties as close as possible.
If you do alot of cutting and joining the video may have audio-sync
problems.
