The Now TV boxes are 'powered by Roku' the Roku kit is Roku
Its surprising how many people get the two confused, i was recently asked to hepl someone get Amazon prime working on their Roku - turned out to be a Now TV box
the Now TV Smaretbox forum is here https://community.nowtv.com/t5/NOW-TV-Smart-Box/bd-p/NOWTVSmartBox DaleC might get some more targeted help in the correct section
Don't worry about it, you will be surprised how many people start a new topic in the wrong section of the forum.
