recently got a TBS 6920 (PCI-E single DVB-S2 tuner). My previous card was only DVB-S but worked fine in media center (the card needed an external power feed to pick up channels). The TBS has no ability to plugin external power. If I scan for TV channels in Media center It finds the card but says it won't be configured as no signal detected. Running the TBS DVB Dream software it finds all channels and reports strong signal and quality. In media center if I do a manual configuration and add the transponders myself manually then I can get the channels including HD ones. Total pain in the ass (I don't understand why MCE can't find channels automatically with this card). Is this normal with TBS cards?
