I had this machine previously connect to HDMI2 port on my panasonic 32" TV. I have now reloacated it to my home theatre with a Panasonic 65" TV through a Pioneer VSX-1019AH-K Receiver with has the HDMI out (to the TV) to HDMI1. But the machine still flicks the TV to HDMI2 on the TV set.

How to I cancel this setting or reset the factory settings so that the DVD/VCR allows the reciever to determine the HDMI input to the TV?
