Before we delve into solutions to fix the PS4 DVD playback issues, let’s discuss the root cause – region restriction. Whether PS4 is region locked or free?
Briefly speaking, PS4 is region free for games. Users can still play digital and physical games on this console carried with them even if they are traveling among different countries. However, DLC for games is region locked. If you purchase DLC on a foreign region PSN account that doesn’t match with the game, you would still encounter issues.
As for DVDs and Blu-ray, PS4 is region locked. The region code of a DVD movie must be the same as the one of your PS4 device. Usually, you can find out the region code number of a DVD disc printed on the back of the case and there are 6 popular region codes involving different regions and countries:
1 - The United States, Canada, Puerto Rico, and Bermuda
2 - Europe (except Belarus, Ukraine, and Russia), Greenland, Turkey, the Middle East, Egypt, Eswatini, Lesotho, South Africa, Japan, and French Guiana
3 - Southeast Asia, South Korea, Taiwan, Hong Kong, and Macau
4 - Latin America (except French Guiana and Puerto Rico), Australia, the Caribbean, and Oceania
5 - Africa (except Egypt, Lesotho, Eswatini, and South Africa), Russia, Belarus, Ukraine, Central Asia, South Asia, Mongolia, and North Korea
6 - Mainland China
