I tried what you suggested, to export original unmodified version but the exact same thing happened when I tried to open it!
Then you have currently no software installed that can open the videos or the videos have become corrupted.
Can you tell us more about what happened, before you could no longer open the videos? Did you just install any update? Run any cleaning applications to free storage? How did you record the videos? Which camera are you using?
Did you previously have additional video codecs installed? Flip4Mac? Perian?
Anything to give us a clue what could be wrong.
Do you get an error message, when you try to open the exported video? What is the file size of the exported originals? Are they large enough to be the full versions?
As a test, download the VLC player and check, if it can play your exported video: http://www.videolan.org/vlc/
VLC is usually very good at playing anything that the Mac can't play.
