Doable with one tuner more, but the question is still, is changing the
primary device faster than changing the channels?

I am a programmer, but I don't know so much about the things that happen
inside the vdr. I have looked already some times inside the source code.
It is c++ like I do it, a skeleton of c++-code with pure c inside :),
but before I spend my time to dig deep enough into it to understand what
has to be changed I want to know, that it makes sense.
