Sorry about that, the crtc is the display controller (CRT Controller). 
it controls the size, timing, offset etc. of the visible part of the
framebuffer among other things.

regarding the pan and scan problems you are having, I'm not sure.  I'm
not really sure how that is handled.  I suspect the movie player may
pan within the actual YUV mpeg frames which the overlay may not like. 
You'd have to figure out how your player does it.  if the panning is
part of the movie itself, I can't see how that would cause a problem.
