We have the OnkyoTX-SR800 receiver connected to an Onkyo DV-SP800 DVD player. The speaker setup is 7.1. We watched "Pearl Harbor" in the DVD's "DTS 5.1" option. WoW! Now my question. The receiver surround option is set to "PL-II Movie". I notice there are more options and have no idea of their applications. Such as "Neo Cinema" and others. Can I get some explanation on the various settings and their characteristics or applications?
