AC-3 means Dolby Digital 5.1, which was introduced in 1995. Relatively
few laserdiscs have AC-3.

"Digital Audio" and "Digital Sound" are the same thing, a PCM digital
stereo/surround soundtrack. Almost all laserdiscs since the mid-80s have
this.

Actually doesn't AC-3 just mean DD? It could be anywhere from 1.0 to
3/3.1(DD EX)

Dolby Digital comes in Mono, Stereo and 5.1 surround flavors. A more
advanced Dolby Digital EX (EXtended surround)codec exists also, which can be up
to 7.1 channels, but is usually limited to 6.1.
This compares to Dolby Pro-Logic Stereo (2-Channels), Dolby Pro-Logic
Surround (4.1 Channels) and Dolby Pro-Logic II and IIx which can be up to 5.1
channels. I personally prefer DTS.
It's only to bad that Sony's 8-channel SDDS system has never been
incorporated into home-audio equipment. A top-spec ES line Sony reciever with
DD, DD EX, DTS, DTS-ES, DTS 96/24, NEO:6, Pro-Logic II/IIx and SDDS decoding
might be enough to make me re-think buying a Sony A/V reciever. Of course, we'd
need SDDS mixes on our DVDs or the decoding would be worthless.

As it relates to laserdisc, Dolby Digital was only used for 5.1
encoding. There are no laserdiscs with DD 1.0 or 2.0 soundtracks. DVD is
the only format to use that.

DD-EX is technically still a 3/2.1 (aka 5.1) format, but with a matrixed
rear center channel. So is DTS-ES Matrix. The only true 3/3.1 (aka 6.1)
sound format is DTS-ES Discrete.

Thanks. Good to know.

I may have missed a vital post here, but what model Laserdisc Player do you
own? It may help in us determining if you have certain features on it
instead of us having to explain everything in every little detail.

Hi Rick,

I use Pioneer Elite CLD52.

I have completed my project (see the thread called
"I finally x-ferred my first LD to DVD"). I think I did the right thing.
Sound turned out to be killer.
