I still consider 48 the final product, I'm just going to modify my edit chain to allow for both a 44.1 and 48 soundtracks. The only video/film formats to support 44.1 are laserdiscs and DTS Cinema Discs and they are long dead. So unless you are listen to one of those or using a PC, you are going to need 48. Everything now is 48; DVDs, Blu-rays, HDTV, streaming, etc. 48 is the minimum default today.
Most people I talk too, burn the soundtracks onto Blu-rays. That necessitates 48, so that's what my target has always been. Chewtobacco brings up good points, so moving forward it will be dual 44.1 and 48 release. 44.1 for you HTPC guys and 48 for the rest.

If we go with 44.1khz for the DTS cinema projects, it'd have to be PCM as I don't believe DTS-HD MA and True HD like 44.1khz.
Please correct me if I'm wrong.
I'd be ok with a 44.1 and 48 dual inventory release. That or good instructions on how to re sample with good quality.
I'm going to experiment and see if my Oppo 93 can play files muxed with 44.1.
As for the JP test in a real cinema, let's just say I still know a few kind people. :)
Dolby Digital and DTS (home theater version) both support 32, 44.1 and 48 (DTS later expanded to 96 but that never went anywhere). I have never seen Dolby Digital encoded in 32 or 44.1 but of course DTS exists in 44.1 on laserdiscs. DTS (theater version) as we know is of course always 44.1. DTS-HD MA and Dolby TRUEHD/MLP supports 32, 44.1, 48, 88.2, 96, 176.4, 192, etc. so they can do 44.1. None of that matters since the Blu-ray format won't allow for any soundtracks in 44.1, not in DTS, Dolby or PCM.
I'm curious about how your Oppo does with 44.1. The Oppo will play CDs so its DACs will support 44.1 and if you bitstream you receiver will support 44.1. I wonder if it will even work and if it does, will convert to 48, will lose sync, etc. Please let me know if you get anywhere with that, borisanddoris.
That's cool about the JP test.

I've had a similar problem when creating a blu-ray image with 44.1Khz track to play on blu-ray players. The only way I can watch it without loss of quality is via PC/HTPC.
That's what I assume would happen. Rockin, out of curiosity what player did you test that on? Did the Blu-ray image play fine on your PC despite being non-spec for BD?

But I want also to make a little provocation: why don't we use sometimes the analog laserdisc tracks? Quality is very good, comparable with the PCM tracks, and they could be captured at 48kHz 24bit, without further conversions, so everybody will be happy! (^^,)
That analog question is a good one. I've capture from LDs at 44.1/16 since that was always my default for LDs but 48/24 would probably be better. Being analog it doesn't matter so the higher the sampling, the better (to a point). That's something to think about Andrea. We should standardize.
I still have the Hitchcock laserdiscs that I need to capture and they are all analog. Sadly capturing analog is where better equipment always shines.

Great news on the Uni Monster front PDB, I look forward to hearing those comparisons. I only have the Dracula and Mummy VHS releases from the "Faces" VHS series.
As for Batman Returns, the Dolby Stereo SR definitely needs capturing, as 99.99% of theaters played this track, the WB archive 35mm print I saw in December played this SR track and had no 5.1, and the 5.1 is based from this 4-track mix. They seem to have gotten the go ahead to mix in the new 5.1 format and played with their exiting mix. Comparing the LD 4ch matrix to the early DVD 5.1 shows everything as the same, except for overall mixing qualities. The 5.1 is obviously more discrete, but the Stereo SR feels more natural and has a better low end I think. Plus being a studio transfer you lose the inherent deficiencies of 35mm optical. (The print had a good deal of sibilance and upper frequency distortion, especially in the end title section.)
Yeah crissrudd4554 was nice enough to give me rips of the VHS tapes a long time ago and life stopped me from moving forward with them. Now that I have "some" time, I first wanted to get the '99 soundtracks (sold my '99 discs a while back), so you can have the BDs vs '99 DVD vs VHS.
That's a good read on Returns. That makes me more excited to get to work on that. I guess you can consider Returns close to the pinnacle of Dolby Stereo (SR) technology. I compared Jurassic Park's LD PCM soundtrack to the LD's DTS and it seems to pretty much be a mix down. I would expect that since I believe JP was mixed from the beginning as discrete DTS and the stereo created after (the old 70mm to Dolby Stereo model).
I remember you saying Batman's 5.1 (DVD snapper) was a bit of an anomaly too. I need to get copies of both Batman and Return's 5.1 soundtracks to sync.
