Final Cut Express prob.

OK, I just made my very first short-film. Shot on a SonyDigital Handycam in B&W & Anamorphic mode. Put together in FCE on my PowerMac. It has come time to export the thing to send to my friends...problem! I export as a QT .MOV file, but there is too much noise...lots of digital artifacts that aren't in the actual footage. When I export as a Final Cut Movie, the proportions are all wrong. Anyone know what I can do?
