If the video card is outputing an interlaced picture, shouldn't the TV 
do the deinterlacing?

I mean the player software puts two interlaced fields of a frame into 
the framebuffer (which would have the "comb" effect on moving elements 
if both were viewed at once), and the graphics card first outputs the 
even lines to the TV, and then outputs the odd lines, so the "movement" 
appears on the screen at the right moment, and therefore doesn't appear
