That's only for analog systems. If you hook two VCRs (video cassette
recorders, not vehicle control rigs :) together, and keep making copies of
copies of copies, you'll end up with very poor picture quality -- I've
seen one often-copied tape that was black and white in the original, but
the one I watched had bright yellow and other colors through it, for
example. The only way to watch it was to turn the TV to b/w.
OTOH anything digital can be copied indefinitely without loss of quality:
put two hard drives into your PC, and copy an AVI file from one drive to
the other and back again several dozen times. The final copy will have a
picture qualty that's just as good (or bad :) as the original's. One thing
that can cause loss of quality is damage to the hard disk, but that's not
usually something you need to consider.
