Just got a DENON AVR-3313ci and would like to use the height speaker option. I currently have a 5.1 setup and would like to add the height speakers. I have a BR player connected to the AVR and have turned on the Audssey DSX "height" option which turns on these speakers. My question is, on the BR disc, do I use the 5.1 audio track or the 7.1 audio track? The reason I ask is because if I select the 7.1 track, will it divide the sound to add the "wide" speakers therefore removing part of the audio track to either my L or R speakers because it it trying to send it to wide speakers that are not there? Or will the AVR send height sounds to the height speakers with the 7.1 track..... or should I just use the 5.1 track? I am really confused with which track to use.
