CS3 Premiere wont import .mov

Hello everybody and SOS.

I am just strating learning Premiere and was hoping to experiment on some video footage I already have of a non montaged video clip.
However, "codec missing or unavailable" shows up when I try to import the .mov files. Quick time refuses to play them either. VLC plays only one of them and on a real slow motion.

The info gives me "24-bit Big Endian" and I am on a MacBook Pro.

Any help?

Thank you in advance
