Export movie from iMovie or AfterEffects to PC compatible file

[NCTRNL]

I am trying to export a movie created in iMovie to a PC-compatible file type. I tried mpeg-4 and it didn't play on the PC. I don't want them to have to download QuickTime either. What file type should I go with?

if you open the movie in quicktime you can export it to an avi file... hopefully they should be able to read that.. but you need quick time pro for it
