The system is as follows:
A samsung tv, a sony blu-ray player, a Marantz 5007, and a universal mx 780 remote.
Every few days or so while watching TV, the Marantz switches inputs and the Marantz screen reads : M XPORT
There is nothing hooked up to the M XPORT.
Does anyone know why this would be and how to stop it from happening?
