Hi, some extension to that idea. What about not patching VDR but the convergence driver?
Just add the RTP- stack to the driver and stream anything which is send to the hardware-decoder of the primary card.
This is PES/PS and MPEG1/MPEG2 in any case, as the HW-decoder can only handle that.
So software-players like mplayer shouldn't have any problem with playing (maybe they'll need a PES plugin ...)

You can add a function like "rtpstream( [serverIP:serverPORT])" to the driver, which could also have the option "off".
So channel-switching, etc. is made by the proprietary software - like VDR - and that software only says "rtpstream ( 10.1.1.1:5004)"
or "rtpstream( off )" to the driver for example.

Anything would be streamed and every software could easily be adapted to that API as it would only need that single function call.
