Our region hasn't had any 8640HDCs for a couple of months - I'm guessing they are all shipping to regions with multi-room DVR. So, I brought home an SA 8300HDC while I wait for them to come in.
I value picture quality highly, both HD and SD, including HD to SD down-conversion to s-video - for standalone DVD recording (Sony RDR-GX7s).
From my extensive A/B compares, the SA 8300HDC beats the SA 8300 at SD output, and HD to SD down-conversion is better yet. How is the 8640HDC's picture quality?
I know this is all digital, but every box has its own settings, compression rates, gamma, etc. Does anyone know if there is an equivalent to Sony's service menu for any TW DVR for calibration?
My progression of boxes in my main Family Room viewing location has been 8300HDC > SMT-H3090 > 8640HDC. My mind wanted to tell me that the Samsung looked better than the 8300HDC, but it could just have been placebo effect (and it was such a relief to get rid of that fugly 8300). I saw absolutely no difference in PQ between the 3090 and the 8640.
BTW, the 8640 is NOT a multi-room box. The 8642 is the MoCA enabed multi-room version.
I used to use the 8300HDC with an SDTV. It had much better SD PQ via S-Video out than it did via component out. In the later stages of the 8300's stay here, and with both of the other boxes, all I have used is the HDMI output. I have no idea what the SD downconversion skills of the 3090 or 8640 are.
AFAIK, there are no "calibration menus" available in any of these boxes. Output resolutions are about the only thing you get to play with.
