So I decided on the Panasonic PT-L500U. Placed on order today. I specifically chose this model for the DVI input and the native resolution. Then when I called Comcast to order the HDTV service, I was told that their cable boxes (Motorola 6200) only support component interface into the HDTV unit! Bummer! My question to all of you smarties out there, will the picture quality suffer? I thought DVI was cable/satellite was the best.
