If there was a shortage, then I don't think that was the whole story.
At the time that Dolby Digital was launched I read an article about it, at the end of which was a brief mention, probably just a single paragraph, about a competing system (DTS) which was about to be released, I'm pretty sure that it named 'Jurassic Park' as the first title, because I remember making a point of going to see it in order to hear the new system. Several other systems were also mentioned, with almost no details given; CDS, SDDS, LC Concepts, and something with 12 inch discs.
The impression given was that DTS was a cheap alternative to the Dolby system, and would be available in two versions, six-channel DTS-6 for theatres that wanted Dolby but couldn't afford it, and four-channel (matrixed) DTS-S (upgradeable to the full six channel version) for ones that were really poverty stricken, and couldn't afford even the full DTS! A somewhat unfair assessment of the system. Shortly after reading this I went to a presentation by Dolby at which their digital system was demonstrated with a clip from 'Batman Returns'. I think this was before any public use of the system in this country. During a discussion after the show, a representative from Dolby accepted that their system was not cheap, but indicated that it was intended for use only in a few 'top' cinemas, and was not expected to be as widely used as it has since become. (I can't remember the exact wording used, but it was along those lines.) I asked about what the implications were for 70mm. They stated that they had no plans for a 70mm digital system, and while I didn't get a definate 'yes', they did rather give the impression that they saw 35mm Dolby Digital replacing 70mm 6-track magnetic at lower cost, in much the same way as analogue Dolby Stereo had replaced 35mm 4-track magnetic.
It was clearly stated that Dolby SR was seen as the apporpriate upgrade path for cinemas which did not already have it (many in this country at that time) with digital being a prestige, limited market product; whether permanently, or just in the short term, I'm not sure. Basically, it was seen as an upgrade for the sort of houses which were already 70mm Dolby six-channel equipped. The Cat. 699 and DA-10 fitted in quite nicely to an installation with a CP-200, aux unit, MPU-1, SRA-5, etc.
DTS seemed to promote their system rather differently; they saw it as being much more widely used. For the sort of venue with a four-channel system with a CP-50 the DTS-S system would have been a convienent upgrade, just bolt on the reader, put the DTS unit in the rack, minimal cabling to do, and off you go. DTS-6 would have involved more work and greater cost, re-wiring surrounds, extra amps, probably new processor, etc.
DTS got off to a good start, with 'Jurassic Park' and 'Schlindler's List', possibly having more installations than Dolby in this country at that time. After that things seemed to slow down, at the same time as Dolby Digital gained popularity, and became much more widely installed. I would certainly think that there are many more Dolby installations than DTS here now.
Shortly afterwards (less than a year?) the demise of DTS-S was announced. I don't think many places ever installed it, I've never seen one. Most 35mm cinemas either stayed with analogue, or upgraded to six-channel when they went digital, sometimes also upgrading amps, speakers etc. at the same time. Of course, in later years, Digital has become much more widespread.
At about this time, I bought several CD-ROM drives, and never found any shortage, if there was one I think it must have been very brief, just waiting for the next shipment to arrive. In an old computer I still have one the Toshiba caddy-loading drives that were used in the first DTS units, and it is still used.
