Most of these laserdiscs are close to the original Dolby Stereo/Mono/etc but those Cinema DTS are exactly what you heard in the theater. No argument about it.

...ehr, can I correct this statement?

The Cinema DTS included in our BD project is not 100% the same of the one heard in theaters, just because it should be converted from 44.1KHz to 48KHz in order to comply to BD standard. Said that, I think we could affirm that it's still 99% closer, and that's more than enough to me.

Obviously if someone decide to make an MKV/MP4 file, and the player reads properly the track, this will be 100% the same.

I want to add a thing: the only 100% laserdisc track that could be used for any DVD or BD(AVCHD) project is the Dolby Digital one, as it's 48KHz even on laserdisc; the PCM should be converted from 44.1 to 48KHz, while the analog could be captured directly at 48KHz but due to its intrinsic nature, it will be not a 1:1 copy as intended in the digital domain; still, a very good quality track!

All very true, point taken and I agree with you Andrea but you get my point.

When you think about it, most likely those 44.1 kHz tracks (either PCM Dolby Stereo/Surround off LDs or DTS Cinema discs) probably started life as 48 kHz (in the 80s and 90s) studio masters. They were just converted to fit to the LD's or CD's audio standards. When we convert them to 48kHz for the BD standard, we are just returning them something similar to the original master anyway.

I think we can agree that done right, switching between 44.1 and 48 shouldn't be obvious to the listener.
