I connected my Sony DVP-NS75H to Denon 3806 via HDMI. I then connected the AVR to my plasma Panasonic TH-50PX60U via HDMI as well. Everything works great except I'm getting macroblocking problem now when I'm watching DVD. Prior to connecting the DVD to the AVR, I connected the DVD player directly to TV via HDMI and I didn't get any macroblocking problem at all.
Is there any of you that have similar issue? Is Denon 3806 known to give you macroblocking problem?

Thanks.
