Hello there!
Sooo... I just encountered this problem.
I haven't recorded Bioshock for 1-2 weeks or so and I decided to do it now.
Putting on my fraps and opening bioshock and discover the horror!
I didn't see the frame rate thing there as normally I would. Well I pressed the record button anyway and tried to see if it would work.
Looking at the video I noticed it was all black, all you could hear were the sounds of the game...

I would like some help on this!
