I'll look for the menu path to the audio settings. I have not noticed a "settings" selection in the main menu ... I admit however I am easily distracted by the different methods to find movies and we find ourselves going off to watch a movie!
14 seconds buffering to get a movie going. I like that. I have not rented a Disney title so far but I am hoping we don't have to "wade" through 5 previews and 2 commercials for quadruple dip catalog titles before watching the movie. They have a tendency to do this on disc based titles and it gets annoying.
By the way, we now have watched 3 movies in 3 days. SD (x2) and HDX. Will try an HD sometime soon. The instant SD on a newer release was very decent PQ. Instant HD should be even better. So far we are very impressed. I now wished I would have bought at least 1 more box during the special.
