All of the devices which I own which still have the old common Netflix UI
(WD TV Live Streaming, Panasonic DMP-BDT220, Sony BDP-S390) and my Roku 2XS are 720p constrained. I hadn't noticed it because I no longer use any of these things to stream Netflix. My devices with the new common Netflix UI
(Roku 3, TiVo Roamio, TiVo Premiere, Xbox One, PS3), the Win8 Netflix app and HTML5 website player running in IE11 on Win8 all get the Netflix 1080p video encodes. A number of people have reported on AVS that their old common Netflix UI devices are 720p constrained, though one person reported that he has two Sony BDPs (S1100 and S3100) with the old common Netflix UI which do get the 1080p encodes (he's 720p constrained in the HTML5 player in IE11 on Win8); another person reports that Amazon Fire TV gets the 1080p encodes, and it has the old common Netflix UI.
Someone on AVS theorizes that support for 1080p is being dropped on all older devices which used to have it; I don't buy it. Netflix gains nothing from that except a ton of pissed off customers and some bad press.
Comments, RokuShawnS, etc?
