How does Blu-ray Disc regional playback control work with the Kaleidescape movie server?
Each M-Class player is shipped designated for Blu-ray Disc region A, B, or C. The Blu-ray Disc region code of the M-Class player cannot be changed by the user. Any M500 Player and any Modular Disc Vault can import any Blu-ray Disc. The Blu-ray Disc region code of the M-Class player may be checked by the Blu-ray movie when played. About 70% of Blu-ray Discs from major studios are not regional playback controlled and can be played on any M-Class player. See this Wikipedia article for a world map with corresponding Blu-ray Disc region codes.
