using the USB cable, sometimes the transfer of video from my Canon\ncamcorder (SD card) to my PC won't work, I get an error message and\nthe video will not download. I've tried a different cable but no joy.\nI've also tried a usb SD card reader but that won't work either, and\nyet the video plays fine in the camera playback. So I'd be grateful to\nhear from anyone with experience of this problem. Is there an SD card\nreader specifically designed to rescue data? I've seen several\nshareware programs about that claim they can rescue data but I'm\ndubious about shelling out money on something I've never heard of.\nI've tried the camera on three different PC's but the video will not\ndownload so it's either the camera or the SD card at fault. A HD\nhardware capture device is out of my budget for the moment so I need\nto rescue video from the card.\nThanks for any advice.
