   CVD subtitles are different in several ways from SVCD OGT subtitles.
   Image comes first and metadata is at the end.  So that the metadata
   can be found easily, the subtitle packet starts with two bytes
   (everything is big-endian again) that give the total size of the
   subtitle data and the offset to the metadata - i.e. size of the
   image data plus the four bytes at the beginning.

   Image data comes interlaced is run-length encoded.  Each field is a
   four-bit nibble. Each nibble contains a two-bit repeat count and a
   two-bit color number so that up to three pixels can be described in
