Hello UNLVCrjChick and loneswaneast,
As far as the Samsung smart tv and the blue ray player, the key would be if they have a built-in web browser. Since every manufacturer has its own interface, operating system, etc., for its smart tvs (and even different systems for different models), there is no way for us to know if your tv supports a browser, but I am sure if you did a search for your model number you could find that out easily enough. If it does, it would really be as simple as going to our website on your tv, logging into your account, and playing the videos. Hope this helps a bit, but the key is finding out if your smart tv has a web browser built in.
And loneswaneast, I'll chime in a bit with the Roku answer. While we more than likely will never be one of the main icons on the Roku screen, just like with the smart tv answer above, if Roku ever decides to put a web browser into their interface, then that will be all you need to view our videos on there, too. Bug Roku to do this...maybe they will respond to the pleas!
