It did'nt work. Same result... only black screen when trying to watch the TV.Can you try to use the default codec's for MP (MPV for video & MPA for audio) in MP setup -> Television?
I tried to enable the digital part of the Hauppauge card again, and then I was back to the "Can not start timeshifing. Unable to create graph" message.
Seams like MP just want tune the chanels right..... Strange when I receive the channels fine with the bundle program
