A:AnswerNo fee to use a Roku - it's similar to an Amazon Firestick in that regard. As long as you have internet service you can use Roku to connect to YouTube and other places. You do not have to watch anything "live" that you don't want to - it all depends on your cable/satellite/internet options, which are separate from Roku.

A:AnswerThe new version no longer has a SD card slot but does have a USB port and a Roku channel for playing the media on it. I don't know what format limitations if any there are because I have not used it that way yet.
A:AnswerHello Mikev52! The Roku Ultra comes with an RF remote. Meaning radio frequency, which uses radio waves to transmit signals to devices. RF remotes do not require line of sight so it can be behind the TV.
