Canon sd600 Videos wont upload to my computer

I have the powershot A620 and I am having the same problem. Pictures work just fine and a few of my videos [like 1 out of every 5] will upload onto my computer after a few tries.

The video file looks just fine when I go onto the file's properties on my computer through My Computer. it tells me how much room it takes up, and it plays just fine on the camera itself. But when I actually try to save it onto my hardrive it shows up as a 0kb file, which it is not, and doesn't actually save as anything. I've tried alternative ways of saving [clicking and dragging, copy and pasting, and saving directly into My Pictures] but none of this seems to work.

This is causing a great deal of hassle so if anyone has a solution to this problem or knows of a way to find one or knows the reason I'm having this problem or knows anything at all, PLEASE HELP!!!
