Help me pleeeaase!

I'm having some trouble with Adobe Premire 5.1, when I import videos (only type that works so far is mpeg, DV don't work nor does avi) for some reason it sort of cuts them up. What I mean is that instead of the 25 fps it says there are thre only turn out to be about 3 frames.

I'm trying to create lightsabre effects by creating a filmstrip file, but when i look at the filmstrip file in photoshop I think that I get 15 of the same image before it changes for another 15 of the same thing. But this happens before i export it as flm but after importing the video.

Any ideas what I can do to resolve this problem? Any help what so ver is welcome.
