I have been nothing but impressed with the quality of the BDP-S770. It is a fantastic Blu-ray, Netflix, Amazon, and Qriocity media playing device. It has just about every feature that you could possibly want, with one exception. One of the main reasons I bought this particular player was for its DLNA capabilities. I have a DLNA media server that has around 400 h.264 movies and thousands of AAC songs and I was hoping that the BDP-S770 would be able to play them through DLNA streaming. This is not the case. At first I was just confused, the device showed all my pictures from the media server, but would not show or play any music or movies. After digging though the manual for a little bit I found a few very curious footnotes. The device only supports AAC and H.264 video through a direct connection! It cannot stream these formats from my media server, which is very disappointing.
If you want a top of the line Netflix, Amazon, Hulu, Blu-ray player .... then this is the device for you. Just dont expect it to live up to the hype when it comes to your DLNA media servers. Hopefully they will address this via a firmware update, which if they do, this would turn into a 5 star review.
