This is probably a bug where the on-screen display is showing the Pause/mute buttons in response to touching the remote. Does this happen on a non-onscreen orbiter too?
If this is the case, then somebody needs to go in with Designer, go to the Non-Pluto PVR remote, 16:9 V2 variation, and remove the goto screen that causes the play/mute butons to show up.
I don't have a designer setup atm.
