I've had my TX-NR807 up and running for a few weeks now. It replaced a DS787.
So far so good. Have had some HDMI handshake issues with my Zune HD, but it looks like reprogramming my remote to fire up the TV first and Zune last has fixed this.
One thing I can't figure out, however, is the Dolby EX setting. I have it set to AUTO, which I assumed would only enable Dolby EX when watching an EX soundtrack (the way my 787 worked). However, Dolby EX is displayed anytime I am watching a dolby digital soundtrack, Ex or not. For example, when watching TV, the display reads Dolby EX.
Am I missing something?
