I have been trying to get an HD PVR working in Windows 7 Media Centre for 2 days, and got to the point where I need to know what the trick it.

1) I've tried using the Hauppauge drivers only, and the device shows up in WMC but the stream doesnt show.  (I confirmed it does show ok in WinTV)
2) Ive tried using DVBLogic software from 1geek1tool... again Tuners appear but stream doesn't.

Has anyone got any hands on experience with these devices?

I am trying to use the composite feed at this stage if that makes a difference.  I understand you can do HD with this, but not a requirement for me at this stage.
