Hello and Happy Christmas to all! I have a Onkyo SR502 connected to a Polk Audio home theatre system (RM7300 with an extra rear speaker) and TV is a Panasonic TH-42PX50U. My first question concerns the listener settings on the Onkyo. The "DTS" logo appears in the Neo:6 mode and the manual reads "This mode creates 6.1 channel surround sound from 2 channel analog sources. My very first questionj on this board, and undoubtably a dumb one - what does this mean and when should it be used? I'd really like to learn what listener settings should be used for hdtv sports, tv in general and music. Also, should my rear speakers (which are mounted in the ceiling above the couch due to the limited size of the room) be angled down and towards the listener, or parallel to the ceiling ? Thank you, Matthew.
