Besides taking longer to render a file( avi to mpeg) does this function make a noticable differance in the final Dvd.

It can. In a sense it is a tweaking process. The first scan analyses the video and determine how best to maximise the quality. The second pass actually carries out the maximisation process. In a single pass encode, this is all done together on the fly, and the maximisation may not always be carried out with optimum efficiency.

Ken is totally correct, but in reality, 9 times out of 10 you won't see any difference at all.

Terry, I beg to differ here.

If you have a video with fast moving objects and also slow moving or stationary sequences, you will certainly see a difference. Maybe not in quality

but certainly in file size
