I'm a newbie to Super 8 films and it's my first post here.
I recently bought the Braun FP3S projector and with some difficulties managed to get a new ligtbulb and a cool film. I tried it out and it worked perfectly fine yesterday. Unfortunately today I played with it a bit and the film got stuck on sprockets. It took me a while to untangle it, but when I played it once again the image was completely distorted. Actually, it looks like there are three frames displayed at once even on the highest speed. You can see it on the video below(three lines of subtitles)
Do you have any idea what might be causing the problem? Everything seems to be working fine. Maybe it is connected with the driving belt?
