(a) frantic worrying because I can no longer play analog sound laserdiscs then
(b) getting rid of some and replacing them with DVDs, putting some in frames, etc. then
(c) saying it wasn't really that important anyway.
So naturally I've now moved on to phase
(d) and bought another bloody laserdisc player.
Found it on Gumtree, bargained the price down a little, and bought it this evening.
This one's a CLD-D925, e.g. about the best one that wasn't ridiculously expensive (it's designed for general home use rather than the laserdisc equivalent of "put the player on a half-ton slab of concrete" audiophile nutters) and plays both sides of discs, analog and digital sound, PAL and NTSC. Came with about 28 NTSC discs, none of which I actually particularly wanted, and I may well end up flogging most of them, that plus selling the old player should eventually pay for this one.
Reasonably pleased, provided that nothing goes horribly wrong...
later - forgot to say that there was one oddity - a boxed set that was supposed to be laserdiscs contained a 5-disc CD collection, "Elvis - The Complete 50s Masters" Not entirely sure what I'm going to do with this, but the next time I run Elvis: The Legendary Tours there may well be a sound track...
