If you simply turn your TV off while the Roku is streaming something, yes it continues streaming until the 4 hour alert is activated to ask if you're still watching. If you first press the Home button on your remote and see the Roku home screen before you turn off the TV, then in general the Roku is no longer using data. However, as long as the Roku is powered on and connected, it does occasionally check the Roku server for updates. Other than that, there's very little network activity from a Roku device.
You cannot disable the auto-update function, so if you want it to use absolutely no data when not in use, you need to power it off.
You didn't mention what model Roku player you are using. If you are using a player that has a USB cable for power, and you use a USB port on the TV to supply the power, then it's likely your Roku is being turned off every time the TV is powered off. If you see the bouncing Roku logo when you power the TV on, then it's turning off with the TV.
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.
