Does anyone have a TT S-1401 working with MediaPortal (or any other DVB application for that matter). I have installed the 5.0.0.19 BDA drivers for the cards (I have tried two) and neither work. I get Graph errors when it attempts to tune to a transponder.

MediaPortal reports 0x80004002, which is E_NOINTERFACE.

Anyone have any ideas, it's driving me crazy.
Thanks
