Hi, I was playing around with the remote control on the E-50 DVD recorder, and I changed from DVD 1 to DVD 2 in the settings menu. My problem: I can't change it back to DVD 1. Every time I press return (or any other button on the RC), I just get the message on the unit display: "REMOTE DVD 2". Is there some way to return to factory settings or return to DVD 1? Thank you.
