Does anyone have a list of DVD's with uncompressed (PCM) audio tracks?

I know the Beatles Anthology has a PCM track.

Criterion's DVD of Ingmar Bergman's The Magic Flute has an uncompressed PCM track.

How would one hear the PCM track? I assume it's as simple as selecting it right? no special connection other than the coaxial digital out? or since this is analog I need a different connection?

Stop Making Sense has one. MST3K: The Movie has one too. I wish we would get more PCM tracks instead of inferior quality AC3 at 192kbps.

PCM is digital. And your coax out will work fine.

A few I can think of...
Pink Floyd- The Wall (very nice- I prefer it to the 5.1 mix)

in the same vein: Roger Waters- In the Flesh (concert dvd)

Paul McCartney's Wing Span (one of the few dvds I know of that doesn't have a DD track- PCM only)

Rolando: you might have to select something like "raw" on your digital input to your A/V processor. I don't know about other ones, but mine require that selection, default to Dolby I think... Other than selecting the PCM track if necessary, that's all.

Maybe it's just me, but I really think it should be standard practice to offer movies with either mono-only or 2-channel-stereo-only (i.e., classic Dolby Stereo) soundtracks in PCM as opposed to Dolby Digital.

Although, in the case of Criterion's VIDEODROME, at least they offered the Dolby Digital 1-channel track at a higher bitrate (192 KB/S, the usual bitrate for DD 2.0 tracks).

Many Sony Music DVDs have uncompressed PCM.

I think (not positive) that the James Taylor live and Bruce Springsteen videos and Live in NYC have PCM tracks ... maybe some of the other Bruce DVDs as well.

I agree that PCM should be used for mono and stereo tracks, although I understand the question of bumping the bitrate ceiling when you get above 2 or 3 channels, particularly if you're looking at 24-bit and/or 96 kHz. Of course, there's no excuse for cutting down a mono or stereo AC-3 track to 192 kbps [the rate used for AC-2 on old satellite TV systems]; my own unscientific A/B comparisons on an unusually-encoded LaserDisc suggest that AC-3 stereo at 384 kbps [DVD allows a somewhat higher rate] can sound very nice.

A few early R2 DVDs from BMG had PCM audio tracks: Manhunter and Flash Gordon, for example.

The latest Zeppelin DVD has a PCM track.

The Star Wars music DVD that came with the Revenge of the Sith soundtrack has both PCM 2.0 stereo and Dolby Digital 5.1 tracks.

Indeed.

Dolby Digital bit-shares accross channels so if there's not much happening but dialogue in a 5.1 mix, the center channel gets to use most of that 384 or 448 kbps for better fidelity...which works great bcs when that's all you're hearing you "tune in" to that one channel.

So if 2.0 and 1.0 DD mixes were encoded at these higher "5.1 rates" the fidelity would markedly improve. By capping a 2.0 mix to 192 kbps a limit is put on the maximum fidelity either channel can ever reach...which is well below what a "channel with focus" in a typcial 5.1 448 mix would be able to use.

2.0 and 1.0 mixes at 448 kbps would probably sound good enough that most of us "PCM on laserdisc still sounds better" guys wouldn't mind so much...though genuine LPCM would still be preferred.

One thing to note: LPCM on DVD can only accept sample rates based on 48 kHz, whereas CD and Laserdisc sampled at 44.1 kHz. This means that many times the PCM on DVD has been sample-rate-converted at the studio to encode it at 48 kHz...which can noticably degrade the sound quality IMO. I've noticed that in general the PCM on laserdisc still often sounds better than the PCM on DVD, I think this may often be why (the sample-rate-conversion issue on the DVD). Of course, if a true A/D was performed at 48 kHz or higher-rate (like 96 or 192 kHz) and then downconverted to 48, it could potentially sound better than the 44.1 on laserdisc.

Curious if true, since professional digital equipment ordinarily operates at 48 kHz, and often at 24 bits; on the other hand, if the final product was destined exclusively for "consumer" use, in the days before DVD [remember prerecorded DAT was 44.1] I suppose it would not have been unusual to record the two-channel master mixdown directly at 44.1/16, eliminating the necessity of downconversion at the mastering lathe. Reconversion back to 48 would be a definite quality drop. Do you have a source?

Not to stray into deeper waters, but I might mention the apparently little-known fact that the home dts audio codec, "Zeta," has a fixed per-channel bitrate: 220 kbps in the original design. Since AC-3 and Zeta belong to the same family of codecs, the two active channels in 448 kbps Dolby Digital should be expected to have sound quality on a par with the corresponding channels of full-bitrate dts, which through another unscientific comparison ["Babylon Sister" stereo mixdown from the Gaucho dtsCD vs. stereo PCM from the "20 Years of Steely Dan" CD] I find to be reasonably close to PCM in quality. [The channel-sharing and peak-bitrate phenomena might also explain the oft-quoted assertion that "DD surrounds a room with sound, and dts fill the room with sound," but that is neither here nor there.]

The Trans-Siberian Orchestra DVD has a 2 channel PCM track. The DVD is pretty good (although it could have been a lot better had they included a whole concert) and I'd recommend it to anyone looking for a nice Christmas themed DVD.
