I have a Roku Premiere+ unit. I want to "cast" video from a travel website to my Sharp TV (not a Roku product). Please pardon me but I am thoroughly confused if this is possible using Roku. I see one comment -for limited casting you can download the Roku app for iOS and send pictures/music/videos to the Roku. What app is that? I see so many.
So, can I cast a video from my PC, ipad or iphone to my TV using Roku? And if so, how?
