Re: TV stream and scrambled channels

I think you're mixing up hardware _decoding_ (which would result in an image ready to present on screen) and hardware _demuxing_ (which "pre-selects") which packets to transmit out of the bda-capturefilter.

Nope, no mix-up. :-) But I haven't considered hardware demuxing. Would a DVB tuner implementing hardware demuxing simply not send scrambled mpeg packets through to the filter graph? Or does it mean that it only sends the current TV station stream through to the filter graph?

If you really have hardware-mpeg2-decoding (which e.g the technotrend dvb-s _premium_ line has) then you're completely out of luck, unless the bda-drivers would present to you some kind of custom interface for supplying descrambling-CWs. I do know of _NO_ card/driver that has these caps (nor do I think there would be a legal use for such an interface).

So how would this work with DirectShow? A filter graph consisting of a source filer (a BDA-hw-mpeg-capture-filter) which outputs decompressed video and audio data ready for rendering and a video sink and an audio sink?
