Did you do 'save as' on Windows Movie Maker? Because that isn't the way to compress it.
Press CTRL+P to save it as a playable file. (sorry, I don't know the english translation of WMM stuff.)

I open the Fraps-saved .avi files in VirtualDub, and compress (Video->Compression) using XviD MPEG-4 Codec, I WOULD do DivX, but VirtualDub yells at me whenever I try saving in DivX, so XviD was my next best solution XD. A nice playable format of under 100mb EVERY time
