Hi ,
YouTube logo will re-appear when a user rollover the controls .
You can hide the Youtube logo from controls by adding an Extra Player parameters modestbranding = 1 in Youtube Component PI advance settings .
This parameter lets you use a YouTube player that does not show a YouTube logo. Set the parameter value to 1 to prevent the YouTube logo from displaying in the control bar.
Note that a small YouTube text label will still display in the upper-right corner of a paused video when the user's mouse pointer hovers over the player.
