Sure there will be one cDvbDevice per adapter for a multi-frontend device
where only one frontend can be active at any time.
If (like on the TT-S2 6400) there are several frontends that can be
active simultaneously, then there shall be separate adapters for each
frontend, and thus a separate cDvbDevice for each adapter.

Note, though, that support for such devices will most likely not
go into VDR for version 2. I'm trying to wrap things up in order
to make a stable version 2, and after that will address new things
like this.
