There are two mainpieces to this that I know of, maybe more.
1) The tuner
2) video overlays
xserver may render video overlays pointless. Once we get hardware compositing
going you should be able to rebuild the entire screen on every TV frame. You may
want to review what is happening with xserver before spending a lot of time on
overlays. How does this play with the current state of XV?
Don't the All-in-wonder boards use the bt8x8 tuner chips? Any idea why the BT
driver in drivers/media/video won't work for the ATI cards? I have the docs for
the AIW but they're in RTF, I'm downloading OpenOffice right now. It might be
easier to just fix the existing BT driver to work on the ATI cards.
I see also that there are drivers for the remote control and TV output. TV out
probably has to be intergrated into the X driver. Remote control should work
standalone.
