I've noticed a weird quirk with my 1050 which is being fed audio from my Echostar 6000 HD satelitte receiver via the aux input and digital optical cable. I have the 1050 in surround mode (natural). When I call up the menu ("guide" button on 1050 remote) on the 6000 and then switch back to the show the volume level is lower. It's almost like it changed modes or something. To get it to go back to the original volume level I can hit the "test" button for the 1050, which happens to be the same button as the "guide" button. If I toogle this button the volume level goes back up. It also sounds like there's more reverb in the audio to, so I'm wondering if somehow it's going between surround and natural modes, even though no change shows up on the 1050 front panel display. Anyone else experience this?
