Oh, I knew I forgot something
Yes, the Saturn plays *.CPK, *.AVI, and *.MOV movies. You can download CPKview (
*.CPK movies) and True Motion Player (
*.AVI movies) from the Saturn Utilities section on the
Miscellaneous page. I'm not sure what can play those *.MOV files since QuickTime didn't work when I tried it. There are more Saturn file types listed there too.
