The GE A950 uses an older method of making a video (Quick Time Motion JPEG).
These are usually output by the camera as an .AVI file or .MOV file.
I can not tell from the User Manual which the GE A950 uses.
We need to know which.

Movie Maker would probably recognize .AVI but I doubt if it can recognize .MOV

.MOV was developed by Apple and you will need to download a .MOV player that can play it on Windows Computers.

You can try using a conversion program that can convert .MOV to .AVI and then Movie Maker might recognize it.
