My cable provider is Comcast. I have digital service and HD package I have a MOT 6200 HD box. I mainly use the box on my new Samsung 3251 via the DVI out connector on the DCT6200 to my HDMI In on TV. The VOD works fine, the menu/info/guide buttons when pressed work fine. I have another TV I've tried the box, viewing channels works fine but VOD and menu/info/guide buttons do not work. The second TV is older and only has a cable input. I therefore use the coaxial in and coxial out connectors on the DCT6200. When I press the VOD button I get two small screens on the top right and bottom left of my TV with some guy talking about VOD from comcast. I never get the VOD menu to choose movies. The menu,info and guide buttons are also useless. I see a light flash on the DCT6200 when I press either the menu,info or guide button but info for current channel or the guide never appear on the TV screen. The menu button also does nothing. I've read in someones posts that the coaxial out on the DCT6200 is analog and wonder if this has anything to do with it. None of the MOT manuals indicate this information. I did have the DCT700 box on the same TV at one point (before my wife made me take it back to save money) and the VOD, Info and guide worked fine. Someone Please help me understand what's going on and if there is a way to use the DCT6200 on my second set and have the VOD, Info and Guide work !!!!
