Yep...it looks like you listened to the movie in Pro Logic II mode even though you may have selected DTS on the DVD setup. If you press the 'Surround' button on the front of your receiver it should toggle between the different listening modes, i.e. DLP II, Dolby Digital, DTS, etc. You can do this with the remote also with the same button. This should match the selection chosen on the DVD setup.
Go to page 31 of your manual and read the part entitled "changing the listening mode', specifically the paragraph "Surround".
The 'Neo cinema' is for playing back movies recorded in only 2 channels and it simulates a 6.1 soundfield and can be used with TV programs and older VHS recordings.
If you got a manual with the receiver I highly recommend you read it. It's a pain in the butt with these new receivers these days but there are way too many features to figure it out on the fly. If you don't have a manual go to this link and download one. Good luck!

Click on 'product line', then 'receivers', then 'TX-SR800', then 'manuals' (down in the right hand corner), then 'owners manuals', then 'receiver' (again!), then TX-SR800 (again!) and finally you can download it (in PDF format so you'll need Acrobat Reader)
