I have a Canon Elph 2 APS camera. After I ejected the film cartridge out today, I tried closing the film door with it empty. However, I then couldn't get it back open again. It seemed like the automatic mechanism that occurs when putting new film in got messed up somehow. AFter prying open the film door a few times, I thought i got the timing right again. and eventually I thought I had it working. So I tried putting some film in. Then I tried to get the film out (as an experiment...I didn't care if the film was wrecked-I wanted to make sure the camera was working properly before I took some important pictures with it and find out later they didn't turn out.) AGAIN THE DOOR WAS JAMMED. This time when I tried to pry the door open, it broke a piece of plastic that latched the film door to the rest of the camera. Does anyone out there familiar with this camera? Is there any way to replace that part?

What's this "film" stuff? Is that some kind of new memory stick format? What capacities does it come in?
