Just received my BDP-S1 yesterday, and got everything hooked up and working soon after. First movie I watched all the way through was 'Crank', after reading the reviews of its excellent picture quality.
All I can say is "Wow!", the picture exceeded anything I had imagined. I am used to watching HD television, as well as upscaled SD-DVD, but the blu-ray picture blew both away.
I'm connected via HDMI>DVI to an 'older' Toshiba rptv (50hdx82). The Sony is set to 'Auto' for picture, and it was coming through at 1080i/60, the max for this set. Audio is run via coaxial digital to my Rotel RSP-1068. (5.1 analogs are occupied by my Onkyo DV-SP1000, which will stay for multi-channel SACD and DVD-Audio.) I really don't understand all the hoopla about the newer sound formats, 'cause to me Dolby Digital and DTS via the coax cable sounded fantastic on my system.
Unfortunately, I still got the copy of "The Fifth Element" inside the box and need to do the firmware upgrade today. However, I did get a little booklet that provides 7 x $10 rebate cards on blu-ray discs from the different studios--gotta like that!
So far I'm lovin' the Sony!
