Query: Works perfect...

...I've had a Panasonic TH-50PH9UK for over two years and I just installed this HDMI card today. I can tell an immediate difference in my HDTV cable picture (1080i and 720p) as well as on my standard Denon DVD player. Easy to install and works as advertised. The urge to upgrade my 1080i TV to a new 1080p has subsided, for now.
