So you opened the TV Configuration, then selected your country and region for your card, searched for channels and keep getting a blue screen. This looks much more like a Terratec driver issue on Windows. Can you check the Windows event manager for details, i.e. faulty module, error number, etc.? All these things are displayed on the blue screen.By the way, the blue screen remains, here is my log.
OK, this confirms that the Terratec driver itself is the faulty component. You don't need to look any further on Windows or MediaPortal level.You smelled the problem.. I installed Terratec's HomeCinema and the same problem happens, at the 6th of 49 bandwith, I get a blue screen.
