Well, I need aid in trying to compress videos so that they're smaller, and I've downloaded three codecs and that Windows Movie Maker. Only problem is, I don't understand how to use the Divx and the Xvid, and when I try importing an AVI file with WMM, it says the file is invalid or corrupted. I'm just really confused, here. Can anyone help me out in trying to make these videos I'm recording (from an emulator) smaller? Is there another codec thing I can try out?

How can a two-minute video be 70 megabytes? o_;
