Photo Booth Recorded Video Problem

I recently bought the imac 27-inch 2.7Ghz. I use Photo Booth to record clips of video from the iMac's internal camera. It has always worked fine for me, I open Photo Booth and switch to "Record a movie clip", then I press record and when I am done I press stop. The clip gets saved on the bottom and i can click it whenever, to review or watch my recorded clip with no problem. So it works as it should.

Now heres my issue, the other day was recording a very important clip on photo booth the same way as I would always do, it was about 15-20minutes long, the only thing is that when I finished recording it, I forgot to press "stop". I closed the window by pressing the "x" on the top left corner instead. Once I did that and had realized I had done that, I went back, open Photo Booth again to see if the clip had gotten saved and it didnt.

So then I went directly to the folder where all the movie clips get saved from Photo Booth and I found the file I had recorded there. I know this is the file I recorded because they get saved as "Movie on 2011-09-05 at 18.58" which shows the date and time. I know this is how movie clips on Photo Booth get saved.

All the other files or movie clips that I've done are in that folder, they show a preview image of the content I recorded for that clip, and the name. Now this last file does not show an image, it just shows the Quicktime icon with "MOVIE" in the bottom and the name of the file.

So now when I clip to open that file it does not open, it brings up a small warning window saying:

"The document 'Movie on 2011-09-05 at 18.58' could not be opened. The movie is not in a format that QuickTime Player understands."

So my problem is, how can I open that file to see the video clip?

I've tried many different ways to try to open it, with iMovie, Photo Booth, iTunes, QuickTime Player, etc and none work.

Doesn anyone know how I view that clip?

Also, when I click "Get Info" it shows that following info:

General:
