Remarks
GPRMs are 16-bit registers that each disc can use in unique ways for temporary data storage.
Note A player application using the DVD Navigator filter does not need to access these registers for any Annex J playback or navigation control. This method is provided for player applications implementing advanced functionality. Do not attempt to modify the GPRMs directly unless you have a thorough knowledge of the DVD specification, and the ways in which the GPRMs are used on the particular discs to be played.
