Hi Dom,
Thanks for your reply. I went ahead and took a short video of the camera running with film in it (running at 8, 16 and 24 fps) and without film (running at 8 fps). I'd really appreciate if you or anyone else could be kind enough to take a look at it. As far as I can tell, the shutter seems to be running smoothly, but I'm no professional :)

This is going to be a long shot, but do you think that this problem could be caused be a lens issue? I've never used this particular lens here (see below), I was thinking because its a wide angle lens, that it may have been "too wide" and caused distortions? Again, I realize this is a long shot theory but thought I'd ask anyways.
Thanks everyone for all of your help so far.
Here's the lens I'm talking of:
