BTW that error occurs whenever I shoot video with my little Canon s100 point & shoot camera, and leave it running too long. It seems as soon as the file size gets past 2GB the file becomes unreadable when the CF card is taken out of the camera & put into any USB card reader attached to computer. The only work around I have found is to put the card in my old Zoom H2 and do a USB transfer direct from it = slow as a wet week but it works! Talk about jumping through hoops!?!
