I think I have a similar problem as the person with the Sony and DCH3200.
I have a Panasonic TH-50PZ750U. I have seen an HD picture on it before and it is amazing, like I am in the studio when watching news, it just massages the eyeballs. I recently switched over to the Motorla DCH3200, and I gotta tell you...while the HD picture is good, it is not great. I have all of the defailt settings, and it just doesn't jump out at me. Pretty disappointing. Anyone else have this problem. Again, the picture is clearer than Standard Def, but it just isn't sharp.
I have a standard HDMI cord between the DCH3200 and Panny, and it is connected to HDMI 1 on the Panny. One annoying thing is that when I switch between HD and SD, the picture goes black for a second and then comes back on. That does not happen when I switch within HD channels or within SD channels. 4:3 overide is set to 480i.
Any thoughts or help will be great. I am trying to find a solution here before having a Comcast rep come out. I really think it is the box.
