I agree on that one!
I had a couple occasions to call them for help.
I had a very strange problem with some USL equipment (a DSP-60) When I called them up and told them who I was they were very helpful. It took a while to get it straightened it out but we eventually solved the problem.

AFAIK the last significant releases "Recorded in Ultra-Stereo" were Kiss Me Guido (gay movie from Paramount in summer '97) and Hurricane Streets (youth drama from United Artists in winter '98).

Aaron S: All Universal releases should have DTS Stereo as well as DTS Digital.

>>Aaron S: All Universal releases should have DTS Stereo as well as DTS Digital.<<

True, from "Jurassic Park" until "For Richer Or Poorer" this was the case.

From "Half-Baked" on, ALL US Universal prints have been quad-format. (The only exceptions I can think of would be Universal-distrubuted arthouse product...)

And unless Dolby made some kind of contractual changes, ALL Dolby SRD prints, regardless of lab or studio, have Dolby SR analog backup tracks.

This reminds me of something I have been thinking about.

How can a film have more than one analoge track?

This is in reference to films such as Space Jam and Jerry Maguire which according to the credits have both Dolby SR and DTS Stereo sound.

This is assuming as Aaron said that all Dolby Digital prints also have Dolby SR.

According to Dolby's specifications, the analog track on ALL SRD prints is Dolby SR.

And the only way a film can have more than one analog track would be if it were a 35mm mag/optical print.

In the cases of the films you mentioned, are you certain it was the 'DTS Stereo' logo and not the 'DTS Digital' logo you were seeing? The two formats have two completely different logos. And, both 'Jerry Maguire' and 'Space Jam' carried DTS Digital tracks, but 'Jerry Maguire' was SDDS/DTS/Dolby SR only (no SRD)

I'll put it down to just in-accurate credits. I think jerry maguire had the dts stereo logo as well as the dolby analog logo.

Michael, I think you may be somewhat confused. Yes that print probably had both Dolby SR and DTS, but Dolby SR is analogue, while DTS is digital. If you look at a DTS encoded print, you can see the dots and dashes of the DTS timecode between the analogue soundtrack and the picture area. This is why the print you talked about was both Dolby SR and DTS encoded. DTS is not analogue but a digital process.

Anyway, what i was going to post in the first place was in response to Leo, in that we have UltraStereo in two of our 4 screens, courtesy of Jack Roe, and it sounds spot on, far superior to our Dolby CP55's in 2 & 3.

OK, OK, OK, lets get this straight.

when the process was first developed only Universal Titles featured the process and it was exclusively only on these prints. No other digital present. What they were doing was this.

First there was two types of dts setups. 6-track and dts stereo two channel matrixed to four disks. These disks were not discrete like the six channel disks. They fed into the processors and were decoded into four channels. This same mix was used to create the analog soundtrack. The two types of logos were created originaly to distinguish between the two types of dts systems.

If jerry maguire did not use dolby digital then it was not bound under any contract to use the sr analog track. Not having a print of this movie in front of me to see, I could not tell you whether it was or wasn't sr analog tracks. My feeling is it could have been dts four channel encoding used for the analog.

By the way, since all major releases have all three digital tracks. I would not see the use of dts analog ever used again.

'Jerry Maguire' had a Dolby SR analog track. Therefore the Dolby logo in the credits.

Darryl: The 'DTS Stereo' logo as it is used today refers to the A or SR-compatible ANALOG OPTICAL track on certain (now almost exclusively non-Bond MGM) titles. The matrixed stereo tracks [via the CD's] haven't been available for years.

Perhaps Karen can referee this one and make an official call on this issue.

I was trying to get hold of copies of the logos so we know what we are talking about. Does anyone have a picture of the DTS stereo logo?

yes Arron I know the discs are not made anymore. I remeber the Flintstones used them because they sent me the wrong disc. That was 1994. My point is that the two logos were origionaly developed for the two different types of systems at the time. Now there should really only be one logo.

The DTS stereo logo was not in relation to the single disk system but to the backup optical track on the print and it could be a emulation of A type or SR
If the film is also encoded in SRD then the backup would be a genuine Dolby SR track but on a DTS only print the producer has the option of useing the encoding of their choice genuine dolby encoding UltraStereo encoding DTS encoding or Panastereo encoding
The disks for the DTS single disk system were labled stereo but the DTS stereo logo was for the optical track encoding

FYI, here are the two DTS logos that I've seen: DTS Digital and DTS Stereo. These are both taken from Hackers, a terrible movie, but one which, fortunately for this discussion, was recorded only in DTS.


By the way, as long as we're on logos, did Ultra Stereo ever have a logo for the handful of films that bore its name? I remember in Robert Altman's The Player, the Ultra Stereo credit was just text -- no logo.

Ultra*Stereo uses the same logo that is on the processors (not the "USL" logo) for their analog sound format.

Michael: Which of those logos shown above did you see on 'Jerry Maguire'?

Tao: there is an alternate DTS Digital logo that I have seen on prints as recent as 'Flubber' it is a variation of the 'flying disk' logo (The Digital Experience)...
