So with my new receiver on the way on Monday, I have been going over the manual and for the life of me can not figure out which settings to use for what. You have Dolby Digital, THX, THX Surround, THX Music DTS, and so on and so on. What settings do I want to use for a movie and concert? I would think the DTS setting would be best for concerts and movies that use that, and star wars would use THX but I am not sure. Can anyone simply break them all down for me?
