P.S. - Yes, the burn speed can affect the play reliability in standalone dvd players, also the brand of blank DVD-R that you use does make a difference. It's a matter of the number of errors created on a burnt disc. Some DVD players have far better error correction and tolerance than others. The easiest route to happiness is a DVD player that is less than two years old, a decent brand of blank DVD, Apple's own, Verbatim or Mitsubishi Chemical and finally burn at the slowest speed your patience will allow!
