When I play a blu ray DVD, TV screen show 'Enter your region code'

DVD REGION FREE & BLUE-RAY REGION FREE
To change the Region code on your DVD player, open Control Panel - System - Hardware - Device manager, and click on DVD/CD ROM drives, then right click on the DVD drive and click Properties then click on DVD Region.
You can enter a new region and it also shows you how many changes have been made.
NOTE you can make only 4 changes and the player will lock permanently on the 4th change.
If you want to play DVDs from any region you maybe able to upgrade the firmware to make it region free BUT if you make a mistake or installed the wrong firmware the player will be a piece of junk.
The best solution to make the player region free is to install a piece of software (Passkey for DVD) that allows you to play DVDs from any region and Passkey for Blu-ray that allows you to play Blu-rays from any region. There are several available on the Internet but my favourite is DVD-Region Free From: -
www.dvdfab.com/products,free.htm

You maybe able to get a region free code from one of these WEB sites.

Commercial DVDs are released with region codes that restricts in which part of the world they can be played. Consumer DVD players sold in those regions are pre-configured with the correct region code for the given sales area. The United States, Canada, Bermuda, and U.S. territories are region 1. Europe (except Russia, Ukraine, and Belarus), The Middle East, Egypt, Japan, South Africa, Swaziland, Lesotho, Greenland and region 2.

1. Leave eject tray open
2. Enter 1369 (default password) and screen will show XXXX
3. Enter 0 for multi-region or what ever region number you wish.

Note: if you take to long to enter code, X's will disappear, but still continue to enter rest of number.

make sure your console has the ability to read region 1 discs in the first place.
REGION 1 -- USA, Canada
REGION 2 -- Japan, Europe, South Africa, Middle East, Greenland
REGION 3 -- S.Korea, Taiwan, Hong Kong, Parts of South East Asia
REGION 4 -- Australia, New Zealand, Latin America (including Mexico)
REGION 5 -- Eastern Europe, Russia, India, Africa
REGION 6 -- China
REGION 7 -- Reserved for Unspecified Special Use
REGION 8 -- Reserved for Cruise Ships, Airlines, etc...
REGION 0 or REGION ALL -- Discs are uncoded and can be played Worldwide, however, PAL discs must be played in a PAL-compatible unit and NTSC discs must be played in an NTSC-compatible unit.
The end result is that DVDs encoded for regions other than Region 1 cannot be played on a region 1 DVD player, also, players marketed for other regions cannot play region 1-stamped DVDs.

If you forgot the parental control code and you need to unlock that, though, then try this:
1.Bring up a screen where the unit asks you to enter in the parental code. You can either insert a restricted disc, or enter the DVD setup menu and go to "parental control" under
custom setup.

2.When the screen asks for the code, press the SELECT button, then enter in the code "7444".

3.The level adjustment under Parental Control dictates the strictness of the player. The lower the value, the more strict it will be. Either increase the value to lower the restriction, or disable the lock entirely by setting it to "off".

4.Once you have made your adjustments, be sure that the DVD tray is empty, and press the RESET button on the front of the Playstation 2. It is imperative the tray is clear of any DVD or game for the unit to save your settings.

This worked for my NS-BRDVD2-CA, basically the same model as yours.
1. Turn on the player.
2. Press the home/setup button and release. Enter 9-1-1-3 on the number pad.
3. "Configure player" appears in the wheel menu to the left of the screen. Using the up or down arrow button on your remote, navigate to it and press enter.
4. Three menus appear on a blue screen in the centre of the set: DVD Region, BD Region, and BD Profile. Select the one you want and press enter.
5. A grey screen appears in the centre showing the various regions. Navigate to the one you want and press enter.
6. Exit the grey menu by pressing the left arrow key, then press it again to exit the blue menu. The screen will appear as it did in step 3 before you pressed enter.
7. Open the drawer and put in your foreign disc. Wait a little bit. When it's ready, the disc's main menu appears. Play it like you would any disc.
8. Voilà! Consider yourself fortunate: You're now able to play foreign DVDs and Blu-rays on your cheap North American player.

P.S. Remember that you have to do this every time you want to play a foreign DVD, because when it's shut off the player automatically defaults to Region 1 for DVDs and Region A for Blu-rays (i.e. North America for DVD and the Americas for Blu-ray). The "configure player" menu disappears sometimes, too; to see it again, simply re-perform the "home/setup, 9-1-1-3" hack.

Some Blu-Ray players will need a hardware mod to be region free.

open tray
enter 0520, then press up, down, left, right (these are the keys around the ok/enter button)
a message will appear on the screen showing current region
press 0 and enter
it should now play any region
hope this helps
