Change the main items to:
<m> Multimedia support --->
[ ] Webcams and video grabbers support
[ ] Analog TV API and drivers support
[ ] Digital TV support
[ ] AM/FM radio receivers/transmitters support
[ ] Remote Controller support
This provides an interface that is clearer to end users that
are compiling the Kernel, and will allow the building system
to automatically unselect drivers for unused functions.
