UPDATE...as of 11/24/15 I am now able to use the remote to control YouTube.
In this video, I describe the features of the new PS4 Media Remote, as well as discuss the pros and cons of it. Does it live up to it's PS3 Media Remote predecessor? Stay tuned to find out.
Note: In order to turn off the PS4 using this remote, you must go to the setting and select one of the power management options (i.e. power down, or stand-by mode).
