I too had a terrible problem with Denon product via HDMI. After contacting them about it my unit was sent in for repair. It returned the same. I needed a player for my reviews, on my site. In a jam I went out and got a SONY, a cheap unit compared to the the Denon - guess what... it put the Denon to shame. The Sony displayed a stunning HDMI picture on my 50' SXRD without any digital micro-blocking. I contacted Denon about this and they had nothing to say. I was sicken by this that a thousand dollar unit was out performed by a $129 one. I also found the Denon incompatible with many dvds = an issue Denon told me over and over was the discs fault. Since then I've re-tested much of the discs on the Sony and found them to now work. From this expericene I dropped the Denon banner on my site.
