This is not correct. I use the Roku website, no Roku device just my PC, and it played 16 episodes of Sanctuary last night, totaling easily 12 hours of viewing time without my consent. No turn off on its own timer. I literally stopped the episodes last night after ending episode 4. I exited the play page and went to the main screen where all the movies and shows are and put my computer to sleep. I woke up just now, and it had played 16 episodes overnight and was still playing when I woke up, even though my computer was asleep and it was not on the play window or even with a show selected at that point. So no, the auto shut off is not a thing.
