MANY tv's will not take under 60hz when connected via VGA, but no 50hz with
hdmi?  That just doesn't make sense.  What would happen if you got a blu ray
player and bought a tv show that was 50fps?  Etc.

Have you tried driving the TV via hdmi at a "real" hdtv resolution (easy one
is 1280x720) and 50hz just to see?
