BTW, IIRC you wrote in linux-dvb that dvb-s2 uses multiple
transport
streams  rather than a single one.
If so it's probably a nightmare to handle.
Do I remember correctly? Can you elaborate?

hmm, sorry but I don't remember exactly.
So, I can make some tests with dvb-s2 on my Hauppauge
hvr4000 dvb-s2 card, but please explain me what I have to
do.

I don't know exactly how it works, but I was under the 
impression that with dvb-s2 you could possibly need
to extract more than 1 stream out of the tuner (vs the
single stream with ordinary dvb)
