If you do that, the class instantiating the videooutput needs to know which 
type to instantiate. If you make a videooutput class universal it is the 
only one who needs to know what outpu tis going on.

OK

OK. ResizeVideo() then? Just Resize() would probably nameclash.

OK

OK, was meant as servide for people implementing keymapping for other modules.

I had that, but then I ended up with the configurations defined in mythlib, 
and you don't want that touched for a single default keychange :-)

WIth my ugly global init-functions only the module itslef is recompiled on 
a change, and a global setup can stil figure out what to setup as long as 
it knows the list of modules.

With all the above there is no need to add the keymap to the context, 
although I agree it 'feels' better.

Do you have any thoughts about PIP support?
