Well it was a toss up between posting in this forum, the cable one or the projector one ... I received my Sony HS50 (latest firmware) on Friday. I've got it connected to my Denon 3910 via HDMI - Supra 12m. When we were watching a movie last night (the first we've watched using HDMI and the HS50) there were a couple of moments when there were blocks on the screen. They were obviously a digital artifact (never seen it with component) and I'm guessing they are something to do with the HDMI connection. The Denon was an ex-demo unit. It passes pluge (which is nice), is multi-region with 04 firmware. I know the HDMI cable is relatively long, but I figured that given it's a £140 cable and the equipment at either end of it aren't exactly budget kit, there wouldn't be this problem. Now, given that all three pieces of kit are new, which is the likely culprit? My money's on the Denon ... hence the post here.
