Roku and Hulu not appearing in the channels?
I searched for Roku, SPINP and Hulu channels under the channel list. It is also not possible to control the volume up or down through the remote control. Searches do not appear in the list.
The channels on the TV screen do not appear to me according to the specifications shown on the device box.
The box clearly says "Channels can change and vary by country" and "TV power, volume, and mute buttons work with most TVs".
So, what country are you in, and what TV brand/model do you have?
(and what Roku device/model did you buy?)
