Ubuntu as a media server

1. If someone wants to use Ubuntu as a home media pc connected to a
tv, there is the problem of overscan; consumer tv's crop off the
border around the image. How does Ubuntu intend to officially solve
this? Right now LinuxMCE has it's own method for doing this so the
LMCE UI is never cropped off, but when the user switches back to
Ubuntu's gnome desktop, the top nav bar is cut off if he's using a
normal tv and not a pc monitor. I'd like to have 1 screen adjustment
tool that correctly adjusts both the lmce desktop and the main ubuntu
desktop, so even when using the Ubuntu desktop on a TV, the top nav
isn't cropped.  Any ideas?
