I was able to play a dvd earlier today, but after I rented a couple of dvds, suddenly the player won't work. It will load dvds fine, but does not respond to the remote. Tried new batteries, and that wasn't it. Tried teaching another remote to see if the remote was sending out a signal or not, and the other remote appeared to learn it fine, so it *is* sending out a signal, but the player doesn't accept it. Normally there is a beep after pressing any button on the remote, but now there is nothing. And without the remote, I can't select even *play* on the manual controls, since two of the three movies I rented require the "select" button to be pressed, which is only located on the remote itself. Has this ever happened to anyone before? What can I do? I got it refurbished in Dec 99, so no warranty. No modifications have been made to it except the firmware upgrade prior to my purchasing it. Any help would be much appreciated!
