It depends really, if you have a lot of cds lying around and you are more of a music person than a movie person then Dolby Pro Logic 2 is the way to go. It is really a trade off you see, if you get a receiver with DPL2 then odds are it will not be 6.1 if you stay in the $500 to $800 price range. So choose wisely my friend, and by the way the 6.1 on the Outlaw 1050 in not discrete 6.1 either.
