Just in case someone could be interested.... it works!
I have bought the T9580 and it works perfectly with ProgDVB
So far I test the satellite side of the board because I haven't got a cable long enough for connecting DVB-T too.
I'm going to replace my old (and no more supported...) Hauppauge Nexsus-S with a brand new TV-tuner card.
I am looking for a hybrid DVB-S /DVB-T card and I have found the DVBSky T5980. In the producer website is reported a ProgDVB support but instead I can't find any references in the ProgDVB ...
