If you play NetFlix through your Browser it auto plays the series. Not sure if it plays all of them with out stopping, maybe only 3 or 4.
I view TV mostly through my Mac Mini, just easier for me since I spend most of my time browsing, reading and editing profanity both visual and audio from a few TV shows to make them viewable for my wife.
I watch Netflix on my tv using roku. It auto-advances to the next episode, but you must push OK on your roku remote to start play.
