* 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.
