I've been looking at the hack list and found a hack for my dvd player, a Samsung 511 (US player). The only problem is that I'm not sure how to put in the code. I do the cold start then press the top repeat button. When I go to put in my code, however, it only lets me put 2 numbers at a time and I've tried every combo I could think of to get those numbers in. I can't figure out how I'm supposed to put the code it at all if I can't put them all in at once, much less see if it works. If anyone can tell me what I'm doing wrong I would really appreciate it. thank you.
