60fps really isn't possible on a 640x400x4 screen.  In ANY interlaced mode,
you're only going to be doing 30fps, because the FIELDS are doing 60fps.
 
640x200 mode will do 60fps fine, because the screen's drawn at that speed.
 
As for DCTV images, they're stored in 4 and 3 bit images, but the "goobers
and twinkies" perform the necessary magic to unpack the extended
information.
 
Position, at least to maintain your screen, is critical.  If anything
trashes the upper left corner, and the left edge of the screen, your image
is trashed.
