I am unable to load video clips (.mov) into Movie Maker. These video clips came for my replay camera taken on the same day. Some of the clips load fine and others don't. I get a pop up message that says the file maybe corrupt or in a format that can't be recognized. The clip questionable clips play fine in Window media player until the very end, last few seconds, when it says that it encountered a problem.

Is the file corrupt and i am outta luck or can i fix it?
