LD PCM vs. DVD audio quality comparison


My priority when watching movies on my HT is definitely sound quality.

Some of the PCM tracks on LD that I would like opinions on are Falling Down, Heat, Commando, The Game, Seven, Miller's Crossing, etc.

I would also like some recommendations on other LD PCM tracks that smoke their DVD counterpart.

Early On; I had Stargate both on DVD & LD. Even though the AC3 LD should have been the same as the DVD.....it wasn't. Switching between the 2; the LD won by a landslide

Kind of a moot point IMO (LD-PCM having better over all SQ while 5.1 formats have a much wider soundstage, and LD being dead as disco)....however one of my favorite LD PCM tracks is on Criterion's 1993 title This Is Spinal Tap, the film's music tracks have a higher fidelity than even the CD/LP did, a robust track.

As along as people still play LDs & purchase them from places like eBay, they are not DEAD!

(shrugs shoulders) I love my LD collection but as a produced and evolving format...it is dead, sorry.

It's really not dead, as long as we remember it.

Not at all, I'm just saying that IMO it is moot because newer formats evolve, this one won't, it is dead from a product point of view. From a user POV...I have 73 LD's and I actually watch quite a few of them from time to time so it isn't dead from that standpoint but as a format that can compete with newer video/audio formats it is out of the game.

But for this thread's topic it still can compete in one way with today's DVD standards, IMO the PCM tracks on the first releases of Jurassic Park (for example) are still WAY above the DTS & DD 5.1 tracks in pure gusto, the bass in the PCM tracks is a real gut buster compared to it's 5.1 counterparts...then again I have always wished for more PCM tracks on DVD titles. The argument against it being one of bit space on a DVD...that didn't stop The Wall from having a very good PCM track AND fairly good PQ plus quite a few extras...just imagine what Two discs could offer. That's an argument for another thread...or is it connected?

The DTS track from Jurassic Park on LD tripped the breaker on a 15-amp dedicated line in my home theater. Ouch!

I was talking about the DVD's DTS track, the LD's DTS track is a hyper sweetened bass heavy monster as well but I still didn't think it was as robust as the PCM track.

I think the Miller's Crossing LD PCM track is superior to the DVD 4.0 track. The DVD sounds like some dynamic range compression was applied compared to the pro-logic track. I like the LD PCM track on Beauty and the Beast better than the DD5.1 remix on the DVD, mostly due to musical fidelity. The same goes for The Lion King and The Little Mermaid, although in the case of The Lion King, I'm only talking about the original theatrical mix, not the Disney Enhanced Home Theater mix, which is a lot more active and is a fun listen on the DVD.

With The Lion King and The Little Mermaid, I even like the PCM tracks more than the 5.1 tracks on the laserdiscs themeselves.

I just dont understand why Dolby 2.0 tracks on DVDs cant be as good as their PCM counterparts.

I can take an audio CD and rip it to my computer in PCM format, and then compress that data to a 192kbit MP3 and keep the sound almost identical. What barely audible differences there are between a 192kbit MP3 and an original PCM audio track isnt anywhere near the huge differences between LD PCM tracks and corresponding Dolby 2.0 tracks on DVD.

Can anyone explan what the difference is?
