I am currently using a Motorola DCT 6200 cable box with my my 4:3 HDTV set. Most of what I watch is not in HD although I do subscribe to the HD channels. However, whenever I switch to an HD channel the box automatically recognizes the signal change as either 720p or 1080i and displays the image in the the proper aspect ratio of 16:9. When a change the channel back to a non HD channel it automatically changes the aspect ratio back to 4:3 which is what it needs to be.(All of this is a good thing I don't mind black bars on top and bottom for true HD programs.) However, yesterday I tried the new Motorola MOXI DVR cable box and was truly disappointed. Every time I wanted to watch an HD program I had to manually go in and change the settings to 1080i or 720p. Then if I switched back to a non-HD channel the black bars would remain there and the picture was very poor quality. I think because the cable box was trying to up convert the 480i signal being sent for the non-HD channel to a 1080i which was the setting I had selected in the box. In addition, the overall picture quality as a whole was not as good as what I had experincced with the Motorola DCT 6200 regardless of which video output and widescreen settings I choose. Also there were horrible delays when changing channels or accessing the menus, none of which I encounterd with the DCT 6200. Needless to say I took the MOXI box back and got my old DCT 6200. DVR is nice but the drawbacks don't outwiegh the benefits. My question is this are there other cable boxes out there that automatically recognize the signal being recieved and switch the output accordingly to either 480i(non-HD) or 1080i(HD). Or am I giving the DCT 6200 credit for something that it is not actually doing. Also, how does this work with Satelite systems are you constatntly having to manually change in order to watch HD and Non-HD in the proper ascpect ratio. Thanks for your help. I'm relatively new and I'm just trying to learn.
