Hi have a Samsung DVD Player and i get a Region Error Message.

You can get a region free dvd player on your computer and then you can play dvd with any region code. You can try Leawo Blu-ray Player which can do this.

There's no guarantee that you can 100% succeed in hacking your DVD player. The more suitable choice for dealing with the region code issue is to create a region free copy of your DVD discs. You can use Leawo Blu-ray Copy to create region free Blu-ray/DVD copies. For a detailed guide on creating region free Blu-ray/DVD copies with the program, check this out: How to Make 1 1 Disc to Disc Blu ray Backup with 1 Click Blu ray Copy...

When a DVD disc is created, it is encoded with a "Region number." The disc will only play on DVD players with the same Region number - for instance, a Region 3 disc won't play on a Region 1 player.
Region 1: U.S. and U.S. Territories, Canada
Region 2: Japan, Western Europe, Middle East, South Africa
Region 3: South Korea, Hong Kong, Taiwan, Southeast and East Asia Region 4: New Zealand, Australia, Pacific Islands, Mexico, Central/
South America
Region 5: Russia and the former Soviet Union, Africa, Indian
subcontinent, North Korea Region 6: China
The only way to get around the region codes, is to rip a DVD to your computer and remove the region code. Then burn the DVD to a DVD R. There are programs around on the net, but I'm not sure it is legal in all countries.
Google for the programs.
A DVD player sometimes allows you to change the region code once. But it not even would allow you to switch back after you changed it once.
