How does Blu-ray disc regional playback control work with the Kaleidescape System?

The M500 Player, M700 Disc Vault, DV700 Disc Vault and Cinema One (2nd generation) can import Blu-ray discs from any region.

An imported Blu-ray movie will play if any component in the system matches the region code specified by the disc. If the disc is not recognized by the Kaleidescape Movie Guide, enter the region code using the browser interface to ensure proper playback.

Blu-ray discs that are played direct from the optical drive of Kaleidescape Alto, the M500 Player, or Cinema One (2nd generation) must match the region code of that player.

About 70% of Blu-ray discs from major studios are not regional playback controlled and can be played on any Kaleidescape Alto, M-Class player, and Cinema One (2nd generation). See this Wikipedia article for a world map with corresponding Blu-ray disc region codes

NOTE: Strato systems do not support the import of discs. DVDs and Blu-ray discs may be cataloged so that they can be shown in the on-screen user interface, just like content downloaded from the Kaleidescape Movie Store.
