I was given a sony dvd player w/o remote and the parental controls are set and I don't know ghe password even if I had a remote.... Is there a way to reset it's settings using the buttons on the dvd player itself? Or how can I surpass the parental lock so I can play movies other than G rated? It's a black sony dvd/cd player model number DVP-NS315 Thank you so much for your time....
