Because of the difficulty in reconfiguring the DTV encoders, most stations are transmitting in only one standard. In the case of CBS and NBC, it is probably 1080i, and for ABC it muight be 720P. The others might be either of these, or possibly 480p for Fox.
The stations then "insert" the program material they have into the frame. They may do this by inserting the 4x3 image, leaving the blank spaces at the sides, or they may choose to stretch and/or zoom, or a bit of both, to fill the screen.
In any case, the TV set thinks it is displaying the full image, so no selection of format is possible (with most sets, anyway)
[/QUOTE]if I use the amps at all the receiver loses the signal completely the only way to receive any signal is to by pass the amp.[/QUOTE]
One of two possibilities are likely. Either the antenna is defective, or there is a strong local station which overloads the preamps, preventing any signals from being handled correctly. If anyone has a third suggestion, go ahead, but this is all I can think of...

Other than that, there is no way of knowing the incoming native resolution. You just need to pay attention to which network you are watching.
The native resolution issues are one of the pet peeves of a lot of HR10-250 users. I frankly don't really care. As long as the receiver does the conversion, it's doing what I bought it for. I think the HD Tivo does quite an amazing job converting 720p to 1080i, but that's just from what I have seen so far.
