This device was sent to me free by Lovefilm as a long time subscriber when my LG streamer became incompatible with the service. I was so impressed with the quality of the device that I later upgraded it to another model in the same range that plays 3D movies ( this one doesn't). I have used the updated model with Amazon Prime with no problem but have no reason to believe that BDPS 1100 won't work as the basic software is the same.
Yes it does, I was sent it as a replacement for my LG Smart Blueray player by Amazon when they said the LG was not going to be supported. I have just logged on using the Sony to confirm, I have not tried it since service has changed so this was also confirmation for me.
