 * The IODVDBlockStorageDevice class is a generic DVD block storage device
 * abstraction.
 * @discussion
 * This class is the protocol for generic DVD functionality, independent of
 * the physical connection protocol (e.g. SCSI, ATA, USB).
 *
 * The APIs are the union of CD APIs and all
 * necessary new low-level DVD APIs.
 *
 * A subclass implements relay methods that translate our requests into
 * calls to a protocol- and device-specific provider.
