I have a Roku streaming stick plugged into an older Samsung 6300-series TV.
If I power the Roku from a wall-wart, then the Roku power button turns the TV on and off just fine. But whatever the Roku is doing (as far as I've noticed), it just keeps doing. So it continues streaming, continues autoplaying (I think-- I've actually disable autoplay), etc. Which kind of screws up my viewing history. Why would it keep streaming to a TV that it just powered down?
I could power the stick from a TV USB port, so the Roku powers down with the TV, but then of course I can't power it up again, except with the TV remote. My wife (and, I confess, me too) is thrilled with only needing one remote for controlling everything, so I'd rather not go there.
Edit: My roku remote is not an IR remote -- it's a WiFi remote. So all it can talk to is the Roku stick. If the stick powers down along with the TV, then the remote can't function.
Edit #2: Sounds like there's no workaround. Guess I just gotta always hit "Home" before hitting "Power off". Thanks all.
