This is just me, maybe its a placebo effect, but I notice that the catermull camera looks better/runs the track better when you film with the source recorder.
It indeed does, because calculations are much more accurate when Source limits its framerate by itself (via its internal recorder) instead of having it set by Fraps (which is external, arbitrary, and not guaranteed to be stable)
Edited:
