Everything is sent 4:3!!!! This lies the problem...

Aren't you unable to squash/stretch ALL 4:3 material including all 130 DirecTV SD channels?
This is not only an OTA problem. It is a problem when either the OTA or DirecTV channel are broadcast in HD.
According to my Panasonic Plasma there are many many combinations of stretching you can do, and trust me I have tried them all. Options for my TV, Tivo and broadcast are as follows:
Panasonic Plasma: Normal / Zoom / Full / Just
HD Tivo: Full / Panel
OTA or DirectTV Source: SD 4:3 / SD Letterbox / HD 4:3 / HD 4:3 Letterbox / HD 16:9
My Panasonic image modes only work at 480i and 480p with component in. 720p and 1080i will not allow switching of modes. So I use 480p for testing.
My point is that it seems that both HD 16:9 and SD 4:3 at 480p is both sent to my plasma as 4:3!!!. Believe it!!!
When I have my plasma at "Normal" mode I see the HD signal at 4:3, and I have to put it to "Full" mode to see the 16:9 image. I also see the SD 4:3 channels at 4:3 in "Normal" mode as well. It is as if all the signals are 4:3, and nothing is 16:9. Try it!!!
It is when you set the Tivo to 720p or 1080i that the signal is sent to the TV at only 16:9 for both HD and SD stations. This means that all stations are stretched into the 16:9 size.
At least in 480p mode for SD stations, I can use the "Just" mode to make it look better than the 720p or 1080i stretch mode. So, I always use "Just" for DirecTV SD stations at 480p, since 720p and 1080i look stretched.
Second point: With the following above to be true, it is the HD stations, whether OTA or DirecTV, when broadcasting 4:3, that send a 4:3 signal with bars on the left and right. So if I set my TV to "Normal", set the Tivo to 480p, and select a HD station broadcasting 4:3, you see two sets of Grey bars on the left and right. The outmost bars are from the TV and the inner bars are from the broadcaster. So when you stretch this, using the TV to Full or Just mode, all you can get rid of is the TV bars, not the broadcast bars. This is where the problem is. Again, try it for yourself.
We need one more mode on the "Ratio" button. But it seems that the "Ratio" button does NOT work with HD, only SD. So not sure how they will accomplish this.
Currently we have:
(FULL) - Display full picture.
(PANEL) - Adds panels to the side to make 4:3 source not stretch when viewed on a 16:9 TV. "Burn in warning!!"
Add to the chain:
(ZOOM) - This will exclusively stretch 4:3 HD signal to get rid of the broadcast bars on the left and right.
Or, my TV needs a new stretching mode to super stretch the sides.
ok. any questions???
