All right, need to see if anyone has an answer to this one..spent three hours with Canon last night to no avail! I have a new Canon G7 and when I shoot video (any mode) it plays fine on the camera, but when I download it to my MAC G5, only the first initial screen shot is displayed and the screen goes blank. This happens in both ImageBrowser and iPhoto. My old G3 and my mothers A640 does not have this problem on the same computer. Additionally, when I download the video from the G7 on a PC...no problem, it plays fine! I have reformatted the SD cards, I have downloaded new software off of canon.com, I have the most recent Quicktime player, etc. etc? I need help obviously....I am about to return this, buy another G7 to see if it is the cameras problem or else I will go to a Canon S5 IS and try that one...any advice?
