Hi Wod,
I've just ordered a Prof Red Series DVB-S2 7300, when it arrives, I'll let you know about my experience.
At the moment I'm usig a
SkyStar HD2 card and also a Hauppauge HVR-4000 card. Both of them works well for DVB-S2 4:2:2 feeds, and also for DVB-S2 HD channels. For 4:2:2 I'm using DVBViewer with bitcontrol codec.
Regards,
Balazs
