The 990 can take care of distance and channel trim settings via 7.1 analog input, as well as bass management (which is likely minimal if they don't have distance settings per channel), so that's not a big deal. As for the lip sync issue, I am pretty sure that the 7.1 Direct input allows AV sync - it's classified as a video input, and all of the other video inputs allow it. I'd have to go into the menu and double-check to be 100% certain, though, as I don't think I've ever used it for that input.
