Question: Unlock Region Code On Sony DVD Players How do i unlock the Sony DVP-NS57P? I have two Region 2 DVDs (Revolver and Johnny Depp's The Brave) and i would like to watch them can anyone out there help me out?
Document: I visited an electronics store recently and brought a few DVDs (both -R and +R) that I made on my PC. We hooked up 3 players selling for about the same price. The Philips player kept stalling and pausing and then stopped completely after a few minutes. The Toshiba SD-4000 was the same, couldn't play my homemade DVDs. I got a little worried.Finally, the Sony DVP-NS57P worked perfectly, no problem at all!
I was looking for a good quality DVD player selling at a good price. Did I get a real winner. The Sony DVP-NS57P/B Progressive Scan DVD Player was perfect. Amazon's delivery was flawless and the unit was easy to set-up and worked like a charm. I do not yet have a wide/flat screen TV, so I didn't want to invest a lot of money in case the unit would not be compatible.
I just bought one of these, brought it home, hooked it up and tried any number of clean DVDs that work fine on other players. None of them worked. The display said either "NO DISK" or "CANNOT PLAY".Maybe some of these work great, but their quality control must not be very strict or this one never would have left the factory.I selected a Sony because I expected a high standard of quality.
Sony DVP-NS57P/B Progressive Scan DVD Player BlackThis is a great medium priced DVD. It has all of the options I looked for except the S Video plug-in. Great sound and picture quality.
I wanted to purchase an inexpensive DVD player for two main reasons: a player that would play Netflix discs without freezing, and a player that would last a couple of years until the Blue-Ray players came down in price.Since I only bought this player last month, I can't judge how long it will last. However, it has been  outstanding at playing the 11 Netflix discs that I've watched so far. And some of those discs were heavily scratched. I'm assuming the progressive scan is what did the trick.
I would never buy this DVD player again, even if it were only $10. The buttons on this player are very slow to respond. Sometimes I'll press the power button and it doesn't even turn on. I often have to hit a button 2 or 3 times before it works, this goes for all buttons, power, eject, etc. There is a definite lag between button depress and response --- this may not seem like that big of a deal but it really is extremely annoying.

For a reasonable price, our Sony DVP-NS57P/B Progressive-Scan DVD Player is a fine DVD player. Let's just hope that it lasts longer than our previous DVD player or at least until we move up to a high definition unit.
This helps quite a bit in home made DVDs that have no menus.Cons:Remote is well laid out, with similar function buttons set near each other but in opposite directions for opposite functions, i.e., rewind left, forward, right. However, like many el-cheapo DVD players, the buttons are too small and one cannot differentiate functions purely by feel.
Answer: I am very disappointed by this machine. It is said All Regions, but is not, and can't find any keys to unlock it. False advertising.
