Well, tell that to people writing plugins for such output devices.
I don't see where *I* would be involved there?!
I want an easy to use hardware output device, and so far the FF DVB cards
served me just fine. The next step in *my* VDR will be an eHD card (as I
already have one). Others may use whatever output device they prefer.
That's why cDevice is a virtual class and allows implementing any kind
of output device ;-)

Maybe I'll even get there one day - but it's no immediate need for me.
Sorry for being a little "selfish" here, but I always made it clear
that VDR to me is a plain, simple digital receiver and video recorder.
Nothing fancy, no bells and whistles, just recording and replaying
video broadcasts.

I haven't seen anything offensive in your posts ;-)
