Hi!

Do you think, there are quality differences on the PCM-Output between several laserdisc players?

As I said before, there is a great chance, I will use my videotrack but X0/OUT/Other PAL-Projects for my german preservation project.
Of course I will capture video also as a guidetrack but it will later be exchanged by another mpeg2-track.
I won't need to invest that much in the player, if only using it for audio. Am I right?

Please help me!

If your discs have no rot spots whatsoever, then the player shouldn't matter in theory.
But in the real world some players (typically more expensive ones) are better than others at reading through rot spots.
If the player comes to a rot spot it cannot read, there would almost certainly be errors in the PCM bitstream as well as visible picture glitches.
(Unless the rot spot happens during a silent moment in the soundtrack.)

Disclaimer: I've never owned an LD player.

However, in practice you must take into account the “fuckwit factor”. Just talk to Darth Mallwalker…

There really shouldn't be a difference, because the data is digital. Whether you use coaxial or optical, the ones and zeros remain the same. That being said, coaxial over long runs can be affected by electrical inteference, but this isn't a huge issue.

MeBeJedi: Sadly, I believe the prequels are beyond repair.
JediRandy: They’re certainly beyond any repair you’re capable of making.

MeBeJedi: You aren’t one of us.
Go-Mer-Tonic: I can’t say I find that very disappointing.

JediRandy: I won’t suck as much as a fan edit.
