On my Dish network, I have overscan on the top and bottom of the screen. I can't read scrolling news, and when on the guide, the "List: All Sub" words are barely showing. This is on TV2 of my DVR. I looked all through the Dish menu and don't see an adjustment. There is also no adjustment on my TV. Any ideas? Anyone else experienced this?

Yes, I have. I simply reduce the vertical height adjustment on the TV a bit. If you're not a tech, like me, that could be difficult as I have many more resources available.
