I work in Higher Ed and we have a library full of LD's. We treat the players like gold, with only one allowed out in the field and the rest jealously guarded as spares, because we can't get them repaired anymore. Long term I hope to be able to play all the LD's into an IPTV server, but there would be a ton of copyright issues to work out...
If you are interested in buying mine, shoot me an email. I have a Yamaha CDV-1700.
