A:AnswerOf course, I bought mine with the TV mounting online and it shouldn't be of any problem. It will work perfectly without problems, but please be aware that the TV mount kit that you buy for it is within the specs of the TV (for ex. the weight).
A:AnswerYes, it took me a bit to figure that out. You can save fav's and then scroll thru them. Say you're watching one channel and you want to do last watched. You left click to access the TV guide and when you select that Chanel then you can go back and forth between the 2.
A:AnswerYou have a YouTube channel for access to YouTube. You have arrows on the remote to select letters to "type" in what you're searching for. But the easier way is sending videos from your phone to your TV when they are on the same Wi-Fi connection. You find the video on your phone, click the TV icon that appears, and it will play on your TV. And Roku also has an app you can download to use as a remote too. Hope this answers your questions! :)
