There's a number of variables:  Stand-alone DVD players are often quite
tolerant of nonsense on discs, and also quite intolerant of other
things.  Stand-alone DVD recorders usually do not record in a standard
DVD-Video manner.  Computer burnt discs may be burnt incorrectly (wrong
file system, multiple file systems with poor file naming choices in one
of them, discs should contain upper-case AUDIO_TS and VIDEO_TS
directories, with all upper-case filenames inside them, the first file
to be played should be the first file actually written to the disc).
Both stand-alone and computer burnt discs may create playback problems
with multi-session recordings.  Computers playing DVDs may mount discs
incorrectly if they have multiple formats on them (Joliet shouldn't be
used, ISO-9660 can be used, UDF should be used).
