I bought a replacement DVD remote control for my Hitachi HTDK170. It's almost identical to the old one, apart from a couple of buttons, but on the rear of it, the model number is exactly the same. The problem is, it does absolutely nothing when you try and operate the DVD player with it. DVD player works fine using the controls on the front, but remote doesn't seem to do anything. I'm wondering if there is anything I need to "syncronise" or whatever, with the new remote since it wasn't the original one that came with the package? New remote (Click for larger image):- Old remote (Click for larger image):- I know its a possibility that the new remote is faulty, but I would like to think it wasn't. Any advice?
