I'm in a PAL country and all of the local broadcasters use MPEG2 not
MPEG4 - so you probably don't care what I say, but I have a 610 and
it looks OK to me. According to this page
<http://www.nvidia.com/object/graphics_cards_buy_now.html> a 610 is
25% faster than a 520 and a 620 is on a par with a 430. Not that I
trust any of these figures. Is there any such thing as a fanless 620?
Is some content more difficult to decode than others? Could you find
that a particular card decodes 1080i NTSC advanced 2x beautifully - until
the action starts? Or the network moves to a more aggressive compression?
