On the Yamaha, don't use the 5.1 processing modes, just press the "Effects Off" button and it will give standard stereo. Or, you can use the Pro-Logic mode, which is meant for 2-Ch processing and gives a decent sound on 2 speakers. I used to watch X-Files on Pro-logic with 2 speakers and it sound great. Of course now it's broadcast in 5.1 in re-runs, or I watch the DVDs in 5.1. The Yamaha also has a cool way of sending a seudo-surround to headphones.
