I have had a 722 since September using an old 4:3 aspect ratio television for TV2. No problems and I have been very satisfied overall. I bought a new Samsung 16:9 aspect HD LCD a couple of weeks ago to replace the TV2 in the bedroom. This TV has basically been in stretch-o-vision mode since it was installed as my wife prefers a full screen display to the 4:3 mode with sidebars (she also does not like to have everything zoomed).
Normally the 722 is kept in dual mode. Yesterday while playing around with single mode and PIP, I went upstairs to see how things looked on TV2. Needless to say I was surprised to see an exact replica of my TV1 HD display with no distortion.
Apparently, while in single mode an anamorphic signal is sent to TV2 which when stretched via the 16:9 TV2 mode converts to the proper full screen display aspect. I have also verfied that if I change the TV2 to the TV1 modulated channel while in dual mode, the same occurs.
It would be very nice if Dish could update the software to allow an option to output an anamorphic TV2 signal.
