section on TV cards

[Jann Roeder]

Hi,
I'd like to suggest an addition to the TV card setup docs.
I think you should add to the documentation that you need to add the 
extmod module to the module section of your xorg.conf file in order for 
overlay to work in motv. This probably also applies to some other video 
apps.
It should also give the hint that it might be necessary to pass the -dev 
option to motv in order to select the correct video card. This is 
necessary if you are using the nvidia driver which creates additional 
cideo in devices. Maybe it should also cover how to make these settings 
permanent using xresources, however I don't know how to do that myself, yet.

Cheers
Jann
