Had the Macbook for a few months now and Apple TV for a year or so...just upgraded to iMovie 09 and thought I would put a few of my 720P video files together to make a holiday video. All went well until it came to outputting to my Apple TV in a format it likes? I seem to be able to out .mov, but for reasons unknown Apple have decided the ATV won't support this...slowly understanding that the whole "Apple" family of gadgets may well not be as compatible and wonderful as they first appeared...any help would be appreciated.
