I am sure I did not have this before I rebuilt the media centre but now I have the above problem. I am using two Hauppauge HVR 3000 tuners for Freeview. I am guessing that the when the first tuner stops being used it stops sending the switching voltage to the LNB. So question is. How to I get it to maintain the voltage all the time? Or is there some other way you keep the LNB powered?

I am using VMC.

Might be possible for you to use a splitter with 'diode switching' (I think that's the right term) and set both cards to power the LNB. Then if one stops the other takes over powering the LNB. It certainly works with Sky/Freeview STB combinations off one dish. Not sure about how cards power the LNB because I don't use that function of the HVR3000.

The thing is I did not have this problem before rebuilt the mediacentre PC. I think it must be a reg key or something I installed which I have now not reinstalled.

I am sure someone out there must have had this problem and fixed it?
