I just received a Casio Exilim for Christmas. I like the camera, but am really confused about something. I can take short movies with the camera. The box said it is MPEG-4 format. BUT, I was required to download an AVI plug-in in order to play the movies on the Mac. But, isn't Quicktime already a MPEG-4 player? Why on earth did I have to download another plug-in in order to play the movies in AVI? It seems weird. EDIT: another annoyance: I already had Divx to play AVIs. But that didn't work. I have to use Casio's AVI interpreter. Again, weird.
