Query: cannot upload video to computer

I cannot upload any video from the camera (a powershot A610) to computer. I can only infer that this is a card problem since I've tried uploading into other computers and have no luck, and also the photos upload fine, just not the video. I've even tried to browse the card by folder instead of using Window's photo uploading tool, still does not work. Anyone else have the same problem?
