DVD-Video discs use UDF with all required data specified
by UDF and ISO 13346 to allow playing in computer systems. The
DVD-Video files must be no larger than 1 GB in size
and be recorded as a single extent in one continuous sequence. The first
directory on the disc must be the VIDEO_TS directory
containing all the files, and all filenames must be in the 8.3 (filename.ext)
format. [Source: Burn World]
