I just got my box yesterday so forgive me if I have missed something. First let me tell you I have a Roku set up as well as this, $99 new toy how can a girl resist... When using the roku I get much better sound, 5.1. I have used identical content, Crackle on both devices playing identical movies, Resident Evil. I get the full 5.1 using Roku but only 2.1 on the Logitech Revue did I miss something in the set up?
