White book CD-ROM

    A more open CD-ROM standard than
   Green Book CD-ROM.  All films mastered on CD-ROM after March
   1994 use White Book.  Like Green Book, it is ISO 9660
   compliant, uses mode 2 form 2 addressing and can only be
   played on a CD-ROM drive which is XA (Extended
   Architecture) compatible.  White book CDs are labelled "Video
   CD".
