Is anyone able to confirm the statement that a recent LD player can
play all Laserdisc titles.

Have there ever been any significent CHANGES (not improvments) to the
standard that rendered older material unplayable on newer players.

I am aware that some players will not play the Analog audio tracks,
but did the analog audio standard ever change?

Just interested in the evolution of the standard.

Cheer,

Ray.

All players will play the analog (or FM) tracks, but players made
roughly before 1988 won't play the PCM track.

Any player of a given standard (PAL or NTSC) will play the video part
of any laserdisc ever made. There is one caveat, some early discs,
such as Discovision and Technidiscs, did not have a Table of Contents,
(TOC) which tells the player how many (if any) chapters there are and
the running time etc. A few post-1985 Pioneer players would not play
a disc without this info.

I thought this was a issue with the prom code and Pioneer fixed these if you
asked about it. The Magnavox/Philips player that were Pioneer based had
such an issue and Philips said that Pioneer found a prom code issue and
would replace the prom at no cost if you returned them. There was
no-recall. Kind of kept quiet.

Steve,

Many thanks for confirming that. I suspected the video standard had
never changed.

Interesting info about the TOC.

Many thanks,

Ray.

The only differing standard that would cause an issue is PAL/NTSC.

I covered that with "Any player of a given standard (PAL or NTSC)" PAL
for PAL, NTSC for NTSC. <g>

Perhaps for the American market but Pioneer made two models for the european
market which didn't play the analogue tracks of old PAL laservision discs
(the CLD 1850 and CLD 2850..... btw. the worst machine they ever build also
in video output).

They luckily understood they made a serious mistake and the next models
(1950 and 2950) are considered to be the best PAL/NTSC player Pioneer ever
made (although I prefer the CLD925).

Roy,

Interesting stuff. I started this thread because my CLD-2950 is up
for auction on eBay (UK) Item # (5796365973) and I have had a few
people asking questions.

Interestingly one bidder has an CLD-S310 which he claims does not
play the analgoue tracks either. I find this very starange as this is
a PAL only machine?

Cheers guys for the info,

Ray.

He has problably an older PAL disc with analog tracks.
According to the link below the player is PAL/NTSC but analog audio only
for NTSC !

I seem to recall an analog audio problem until I discovered that some audio
outputs were digital only and I had to switch the cables to get the analog
track on older discs.

Not strange actually, since I remember reading about that when I was
looking for entry level PAL/NTSC-player ten years ago (310 was around
1995 cheapest Pioneer player in Europe before 315, and that is true, 310
is PAL only) and bought the next model, CLD-S315. That machine also does
not play analogue tracks on PAL dics. So, we have now 4 european models
without PAL analogue audio. I guess the logic in this was that they were
entry level players and PAL analogue discs were at that time already
rare, no-one would propably want to play them.

I've NEVER found a player that REQUIRED a TOC. That's an interesting
thought.

So the REAL answer...

In Eurpoe, when LD was introduced in 1981, it had Analog only. In
1987ish, they discontinued the format. It was reintroduced around
1990, but this time the discs had Digital Audio only. The discs and
players were NOT compatible. Some (but not all) of the PAL players
could play the analog audio of older discs. You had to be careful.

In the US, there are only changes that affected "compatibility"
between players and Discs.

Players prior to the release of the LD-900 (introduction of Digital
Sound) cannot play in stereo on discs encoded with AC-3 (Dolby
Digital). Further, on AC-3 discs with an audio commentary, playback
on pre LD-900 units will not get you a film soundtrack at all.

The other "compatibility" issue affects discs manufactured after
around 1992. Manufacturers removed a "pilot" signal which was
required for only the PR-7820 player (the very first LaserDisc player
ever). Without the signal, the player is unable to determine CAV vs
CLV and has other playback 'issues'. The disc will still play, but
you cannot perform any functions other than scan and play.


Later in this thread there was a discussion about players with PAL
audio playback issues. I have the DVL-919E player which is a Dual
Format Combi player, DVD/LD with PAL/NTSC playback. It will play any
disc I put into it. PAL-Analog, PAL Digital, NTSC Analog, NTSC
Digital, LaserDisc or DVD. If you can find one, pick it up.
