Hi all. Purchased this AVR yesterday and cannot output 1080p via the xbox only 1080i. Its really fustrating me now, have swapped HDMI's cables and ports but still unable, changed alot of settings on xbox and AVR still the same. Any ideas on fixing this would be highly appriciated. Another issue is with my cable box which only outputs DD 5.1 via Optical and not HDMI, I have plugged both in and set the digital resource to Optical, but still only outputting in Dolby PL 2. Apart from this everything is ok. But if I dont get these issues fixed soon i think I may have to return it.
