No PVR clients have been started

A fresh install does not do this, maybe you should ask mcobits because his retropie script makes some very invasive changes to the system configuration which can cause a number of issues. (this will be the subject of another post in his thread when I get the chance to go through and catalog all the problems I’ve found with what his script is doing)

I would suggest trying a fresh install without retropie and see if it still happens.
