Hi Tom, thnaks for your reply, I'm sorry but I really dont understand all the stuff about movie formats. I have previously just loaded bits of movie clip into my Mac with no problems. The file name is in the format MOVxxxxx. I am loading direct from the camera, a Sony, via the camera connection kit. (Fancy name for a tiny plug). And that's another niggle, the card reader doesn't read my card because it's not of the right type. No indication on the package that it is not universal. However I digress.
Stephen, not sure if they will load into iTunes 'cos I don't know how to do that. Usually I just connect my camera or card to the Mac and iPhoto takes care of all the rest. But thanks for your input too. Guess I'll have to learn about formats and buy a converter - or not. My movies are not going to cause Spielberg any sleepless nights.
Wilf.
