    Just picked up a new (expensive!) Motorola 5100 digital HDTV cablebox for my Toshiba HDX 57" TV. In the cableboxes menu a number of questions are asked, but most I didn't have to worry about because they had automatic settings. However the first three questions were specific. Question #1 asked about screen size - no problem her as the TV is widescreen so I chose 16x9. The second question asked about the scan 1080i, 740p, 480p, or 4801. I chose 1080i. The third question (and the one I am having trouble with) asked for 4:3 override. The choices are 480i, 480p, and OFF. I initially chose off, but this threw my Toshiba stretch modes out of whack. eg. the theatrewide #1 mode, which is supposed to be for 4:3 TV stretch abnormally. This was solved when I selected either 480i or 480p for 4:3 override. My question is what setting should I leave it at 480i or 480p? I think most regular TV is 480i, but if I choose 480p will the box upconvert, and is this good? Also if I am receiving another HD signal (eg. 740p) do I have to go into the box menu and change it manually from the 1080i setting?

    480p= Progressive Scan or Line Doubler
    Turn this setting on.
    No it will auto detect the signal. You cannot get 1080i out of 720p. Whatever they are streaming you will receive.

    Thanks. If say Fox is broadcasting something other than 1080i, my cablebox will pick it up and display it at its proper level, or drop it down to 480i? Also how can a cablebox change 480i to 480p?
