I thought the "... they :) ..." referred to MacUser not knowing why
they, themselves printed it - that they in fact knew the video was
handled differently.  Now I see that you meant Apple had explained to
MacUser who apparently wasn't listening.

I'm not satisfied either, just knowing that it's different.  Can
anyone explain how (and why)?  Is the internal video handled
differently than a card in the direct slot?
