With the upgrade a few days ago, I lost the ability to "Zoom" the aspect ratio on 4:3 programming so that it fills the screen, using the LG TV remote. I don't want to stretch it; I want to zoom it, and I don't care that I lose the top and bottom of the picture. I could do this before; how do I get it back? I have the FIOS settings on 1080 HD, and have the "stretch" turned off. I have an LG plasma.
