Panasonic DMR-ES20K DVD Recorder
No Password to change settings
Purchased the unit and went to play a childrens DVD and it will not play because the ratings setting will not alow it to play.  Attempted to change the ratings setting and was prompted for a password.  Have never setup a password and the manual does not list a factory preset password.  Turns out the ratings setting will not alow ANY DVDs to play.  This is junk!  Do not buy.  How can I unlock this stupid machine?
