Hi i bought this remote hoping that with it i wouldn't lose it, but i cannot program my samsung dvd/vcr combo. It isn't a very old, 2 years max, player plus the tv i was able to code is 15 years +. I've tried all of the codes and none seem to work. I've even tried the manual way of finding the code by holding the code search button, pressing vcr, and pressing the power button until it runs out of codes. Should i just give up?
