I trialed both PlayOn and Anystream. I like the credits with no subscription deal. My biggest issue with PlayOn is the audio quality. I downloaded 2 Star Wars episodes at 3 credits and 1080. 2 ch stereo was what I got.
Anystream 1080 and DD as it should be. Anystream would not connect to Netflix while PlayOn will.
So PlayOn will be used for TV shows and old movies only.
