Why is it that when I encode a divx file (in .avi format) using TMPGEnc, I get white squares appearing at random now and then?

This spoils the quality of the movie


Also, I have a couple of .avi files that are at pretty low fps of about 15-20.

TMPGEnc wouldn't open them.

How do I increase their fps so that TMPGEnc can encode them and then I can burn them into a video cd?

Thank You!
