Input:
I bought this DVD player not only because it was cheap, but also the salesman told me that I will be able to play any DVD from around the world (Regions from 1 to 9) if I set this code 8421. He tried it in the DVD player AD-1200 and wow he was right!!! He also showed me the Macrovision function and I was quite impressed, but something is wrong with mine because I can play only DVD Region 1. Someone told me new ones have limits but I'm not sure. Other than that, it works ok.
