I've seen reference to Region free hacked firmware (for the 2910), but what about bug fix firmware updates? I just scouted out Denon's site, but I do not see anything along the lines of a downloads section or updates page. Am I just stuck with what came on the player or can it be updated? I currently own a 3805 receiver and 2910 DVD player, but would like to be able to keep them current. Further, how do I check to see what firmware I currently have?
