There are no problems with original UMD Video Disc.
But video-UMDs are region-locked.

• Region 0: Worldwide
• Region 1: United States, and Canada
• Region 2: European Union, Japan, Middle East, Egypt, South Africa, and Greenland
• Region 3: Taiwan, South Korea, the Philippines, Indonesia, Hong Kong, Malaysia, and Singapore
• Region 4: Australia, New Zealand, Pacific Islands, Mexico, and South America
• Region 5: Russia, Eastern Europe, Pakistan, India, majority of Africa, North Korea, and Mongolia
• Region 6: Mainland China

All thanks to Sony.
