John Omiatek at QRS (tel.: 1-814-676-6683) is the guy to talk to about
these Universal player systems.  Universal players and nickelodeons do
unfortunately have pouches with a "Perflex-like" material.  I recall
ten years ago, in one of these modern nickelodeons, having to replace
disintegrated Perflex pouches in order to get the rewind to work.
