One of the factors the affects the life of already recorded materials
is the slow speed of the consumer machines combined with mechanical
tape tension.  The tension, made even worse sometimes by normal
temperature fluctuations, causes the tape to stretch over time.  Since
the tape speed is so low, this warps the timing track, and the result
is glitchy video.  VHS is worse than BETA in this respect, since the
VHS system inherently puts more tension on the tape due to its
"double-U" tape path.
