My remote suddenly stopped working. I changed the batteries, but that didn't work, so I checked batteries in a different device & they worked fine. I then used a Q-tip w/some rubbing alcohol on it to clean the battery chamber, let the remote dry, replaced the batteries, but it still won't work. I can manually use the play/stop controls on the device itself, but am unable to use any other features. The remote won't work whether the dvd is bought, burned or rented.
