reddice - its not baloney - different devices in different locations connect different to CDNs.
My Chromecast and Rokus connect to different CDNs (mainly Netflix, Akamai, Level3) and unfortunately have struggled to get above the 240/480P streams for the last few weeks. I have say if the Roku and Chromecast were my only devices in my location I would be like others here and ready to cancel Netflix. Until the turn of the year both Chromecast and Rokus were getting highest quality streams.
