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.

There are computer programs capable of remove the region code from a DVD, but the result should be burned on a new DVD. Most players don't allow a change in the region code more than once. So on your player nothing to hack. Sorry

For all other options, please use Google.

BD media does have region codes. But, unlike current DVD players, the region codes for BD media use letters instead of numbers to indicate a particular zone or region where the discs can be played.

The BD region codes are as follows:
Region A: North America, South America, U.S. Territories, Japan, South Korea, Taiwan, and other areas of Southeast Asia

Region B: Europe, Africa, Middle East, Australia, and New Zealand.

Region C: Asia (except for Japan, Korea, Taiwan, and other areas of Southeast Asia)
