Error Codes
If the property fails, Err.Number may be set to one of the following values.

Remarks
This property is read-only with no default value. The identifier (ID) number is not truly unique, but it is unique for all practical purposes. The ID applies to all replicated copies of a disc. In other words, all copies of a specific movie have the same ID. The ID is based on file sizes, dates, and other information, and not the BCA value.
Example

strID = VidWebDVD.DVDUniqueID
