Welcome to the forum.
The MOV file extension is but a "wrapper," and almost anything can be in that wrapper. This ARTICLE will give you some background, and will also tell you how to "peek inside" the wrapper. What is the CODEC of your MOV files?
Also, note that there is a big difference between using a simple player to play an AV file, and editing that same file.
Good luck, and please let us know more,
I got the G-spot and if I am reading it right the video was opened by cyberlink MPEG-4 splitter (PDVD10) I think I am over my head. All the videos I have will be the same. They were recorded on the Nikon coolpix 7600 camera. So they are not HD. They have only one channel of mono sound. Recorded at 30frames/sec.
