hi all - i just realized something. i have an onkyo 646 which has the multi-channel input. i have my sony 560D dvd player hooked into the receiver using those inputs. what i noticed is that when i select the multi-channel input on the receiver, i can no longer select (via the osd) the surround setup option. it just goes away. as soon as i select a video input the option comes back. so that leads me to believe the test tones from my dvd player (and therefore the sound levels) are the ones being "used" by the receiver. does that sound right to you? i hope this makes sense... ------------------ You step in the stream, But the water has moved on.
