Roku has some channels that are hidden and not immediately made available to all users. These are usually channels that are being beta tested. To access these channels, go to my.roku.com on your phone or computer and sign into your Roku account. Choose to Manage Account and then add a channel with code. Enter your channel access code and hit the Add Channel button. A warning message will appear, but just hit “OK” and “Yes.” Then when you fire up your Roku box, go to Settings, System, System Update, and Check Now to sync up your new channels. Some interesting channels to add include The Space Opera Channel (society), Nowhere TV (NMJS5), RokuMovies (zb34ac), Silent Movies (RLQXKG), and Pro Guitar Lessons (ProGuitar).
