glenee,

Care to expand on that?

Despite a whole series of email messages to Onkyo Support where I specifically asked what problems are solved, and/or what functionality is added, by going from 1.01 to 1.05 I was never told. All I got was "what problems are you experiencing."

I've done a fair amount of searching, including the oft-referenced 886 thread over at AVS, and I'm none the wiser.

Mine has 1.01 and while I could certainly think of some functionality that I'd like to see added in firmware (mostly involving Audyssey) I can't say that I have come across any problems. But then again, and getting back to Onkyo "Support's" reply: I don't think it should be up to me to have to identify a problem before Onkyo will tell me whether its part of their existing firmware fixes - or not.
