Greetings- My father shot some video of my wedding this past weekend on his newish Canon SD870is camera (3 months old), which seems to save videos as AVI files. I have the same camera but just got it and haven't really used it so I don't know it's ins and outs. He was using an 8gb Sandisk Extreme III card when he shot the pics and vids he took. That's a good quality card AFAIK, so I'd hope he wouldn't be having issues. He is telling me that he's not able to copy the larger video files off the camera. For instance there's one that's almost 2 gb and he gets nowhere. He also stated that some video files that he did copy, when played on his Mac, had no sound. He has tried on both his Mac at home and his PC at work. It just seems to not make any progress when importing via iPhoto or when doing a simple copy/paste from the camera. He has tried 2 different USB cables as well. So we know it's not that. I told him to try the card in a card reader when he gets home (he's got one that is embedded in his HP multifunction printer) so he will try that tonight after work. I am wondering if anyone has any other suggestions on things to try to get these files off the cards, or if anyone has any clue why there would be problems in the first place. Thanks!
