Try taking the card out of the camera and loading the videos from the card directly into the reader itself, by-passing the camera.
I have the same problem with my Canon
PowerShot SD1200 IS. It will off-load pics, but not the video. I have an external card reader that handles the videos separately.
No need for cash.
Besides, you end up wearing down the camera's battery when you should be using it to record fun things like beer being bought and consumed. Eh?
