I have recently come across a few video files that for some reason do not play to their full length. These are 97-180 meg files but for some reason the play head on quicktime advances across the timeline much quicker then expected. Reaching the end somewhere in the middle of the movie. Now this is the weird part... If i rewind it rewinds from the end of the movie back through parts that did not play the first time through. Anyone have any ideas. I tried putting it through cleaner 6 but that didn't seem to change anything
