I have a samsung BD c5500 bluray player. When I try to play movies it says mismatch disk and region code. How can I fix this?

No. Blu-rays cannot make region free.

Are you sure that your Take That Blu-Ray disk is playable?
Test it on tha player of a friend

No region hack code to Blu-Ray players.

Try this code I have got it with this code may be you will also get yourthe code is: BD-E6100/XU.Perfectly I don't know whether it is for all regions or not but try this.
Performance Chip

These units are generally hardware modified to make them multizone. It may be that the newer discs use a slightly different zone coding and the modified hardware cannot handle this.

hi,
try the following

As I live in Kazakhstan my BD-C7500 is locked to DVD region 5. Just use the codes at the end of this tutorial for your own DVD region.

1. Ensure that there is no disk in the tray.

2. Switch the player on.

3. Wait until the main menu page appears and the player stops doing anything.

4. Press the REPEAT button - just above the TV channel selector at the bottom right of the controller - and enter 5 6 7 3 2 on the number pad.

5. The region code "3" should appear at the top left corner of the screen.

6. Quickly enter a "9" to make the player region free. (Just try pressing 9 on the remote controller until you see 9 appear in the upper left corner of your TV screen.)

7. Open and close the disc tray. Power down and power up again.

13. Play a foreign DVD to verify the change.

For people from other parts of the world, all region codes are as follows

1 - 2 9 3 3 4
2 - 5 7 5 3 8
3 - 5 6 7 3 2
4 - 7 6 8 8 4
5 - 5 3 8 1 4
ok

Will your machine play standard movie DVD discs? if it does then the laser pickup assembly is the problem. The blue ray discs require a higher precision tracking to offer better resolution.

Remove the disk. Go into the player's setup menu. Disable BD-Live. You may also need to clear the player's memory (maybe called cache, but depends on your manufacturer and model).
Now insert the disk and it should load right away and play normally. This is happening because new disks are trying to use the internet to connect to a server to download new features for the disk (that's BD-Live). This would be cool, except that in some cases it causes this freezing problem where you can't even watch your movie.
Firmware updates don't seem to fix it--at least not yet. So far this seems to be a combination of a coding issue on the disks and perhaps firmware that doesn't know how to deal with the new code. Please post a reply if it works for you.

My dark Knight DVD was only playing the first 4 screens and I burned the firmware upgrade to a CD. It took about 20 minutes from the time I inserted it for it to be complete, then it stopped at 4 again but took about 30 seconds and it began to play perfect.
