Remarks
This method is not required for any DVD navigation or playback functionality using the MSWebDVD object. It is provided for those with a thorough understanding of the DVD specification who want to implement advanced features. GPRMs can be used to hold any values, so they can be freely set and read. But since GPRMs are used to store disc commands as well, changing their values using SetGPRM can result in unpredictable behavior.
