Just read through this thread and I had a thought for Belgand. Have you tried connecting your television audio to your 1070 via a digital connection? If you are receiving digital cable, your cable box should have a digital audio output. When you see shows, especially movies and sporting events, that advertise either "Stereo Sound" or "Surround Sound", you have to have the box connected via a digital connection to receive the Dolby signal the station is sending.

Of course, this only applies if the station and your cable company are sending the signal properly. That's a whole 'nother topic.
