1. presently more and more on my old sets I see both commercials and some shows on digital channels broadcast in letterbox fashion..a:When viewed on your 16:9 set do those images commercials and programs fill the screen ??
b: When viewed on your 4:3 HD set do you get letterbox bars or full screen with those commercials, and channels ?
2.When the switch to all digital transmission occurs how do the broadcasters intend to send out their signals ?:
a) Letterboxed in 16:9
b)Fullscreen in 4:3
The comments of those of you who actually watch standard TV on your HD sets will be most welcome.

These are non HD commercials. If you see them on a SD channel, you will get letterbox for a 16:9 screen and bars top and bottom with a 4:3 screen.
For an HDTV and an HD channel, you will have black bars top and bottom and on each side. Some programs are SD upconverted to 1080i, Discovery channel in Canada carries them frequently.
True HD is 16:9 display.
