I’m having trouble downloading videos from my new Canon PowerShot SD700 IS. It only happens if the videos are really big. I connect the camera and it downloads any pictures and short videos I may have, but not the large ones. It uses a small SanDisk 1GB SD card, but I don’t have a card reader, so I can only try to download by connecting the camera directly to the computer. I tried 3 different computers already. I haven’t been able to find anyone with a similar problem online. I have a video from Emergence 06’s keynote that desperately wants to be free. Any ideas???
