Per,
If you pay the shipping I'll send you a quart of Filmguard to try out. Keep in mind though that if you don;t haev a KElmar type film cleaner you'll hvae to apply it by hand. This is a bit difficult to do. Let me know what you think. Personally, I'd get two more DP-70's and send the Cinemec on its way. If you do put digital on the Cinemec then use a Cat 701. When you do send the machine to projector heaven you will still have the intact digital system you can install on the new machine.
We are developing an SRD reader to retrofit onto the DP70 sound reproducer. The main problem is that you have to go to a sound drum in which the film overhangs the edge so you can scan between the perfs. This gets away from the non-contact type of drum which this reproducer is so famous for. We are trying to work this out so we can use the non-contact type but it only leaves a bit more than a millimeter to support the edge of the film. It does work ok and has low error rates but we're concerned about supporting an edge this small. Cinemec also does it this way...with a 1mm edge for the film.

Well, with all due respect to those concerned, I much prefer SRD to DTS. It sounds better (IMHO, of course), and it's available without having to call the ditribution company for discs. If they have them.At the Göteborg Film Festival three weeks ago, I screened 66 35mm prints (and one 70mm print) from all over the world. Of these, about half had SRD tracks. Exactly _one_ print came with DTD discs even though about nine or ten had the time code track. Thankfully, most, if not all, of them had an SRD track, too. Please note that these prints were shipped directly to us from various film festivals, labs, or special screenings. Also note that most of our screenings were the first European or Swedish screenings of the films in question. We had a few world premieres as well. So what became of those DTS discs? Is it our responsibility to see to it that the film is actually delivered with the digital sound track? I rest my case.

Ari tells about missing DTS discs.
It has and sure always will be a problem, because to few employees at the distribution offices appreciate the added quality, but only gives thoughts to their extra work, delivering not only film print but discs.
Often, some danish bookers have given us the message, when complaining, that if a cinema has installed both DTS and SRD, they see no reason, sending us the discs - we can run digital whatsoever...! (It goes better now than 5 years ago, though !)
Luckily, Karen and her collegues in DTS' former Brussels office and nowaday their English department, don't shy the trouble, but has been helping me several times with discs coming across the sea, so that the best possible presentation can be done. -Just as their patience was far beoynd what you could expect about all my questions during a period some years ago with very poor dealer/service possibilities local in Denmark.
That was great service to a small custumer, and the #1 reason, i ever considered to go digital on my humble 39 seat screen 2.
Thanks again !Per P.S.: Only DTS disappointment: trailer discs not available i Denmark, except a single go back at the start of DTS.... P.P.S.: About that photo of Yours, Ari - Are You keeping birds in the booth in Göteborg ? -Can't help thinking back on Hrundi v. Bakshi and his "birdy-num-num"...

Ahhhhh...
This debate is like taking both Coke and Pepsi into an uncivilized culture and asking them which one is better?
The "average" (by that I mean 99% of moviegoing patrons) CAN NOT distinguish a difference, nor even know what unit is running in what auditorium... Just so long as it's digital.
I must say, that I think of myself as having a rather keen ear. I played piano for several years, have been playing guitar for two years now, and have worked various a/v tech jobs aside from running my booth. I have noticed that DTS dialouge (high end) noise seems more crisp. Dolby managed to sneak in their old-school "noise-reduction" into SRD, which muffles the higher end frequencies so as to rid the sound of that famous hiss. DTS does not do so, making things like dialouge or a symphony orchestra sound really *REALLY* good. However, the special effects I have to give props to Dolby. Everything other than the center channel sounds GREAT. Extranneous noises such as a car blowing up shake the seats, instead of a crisp clean fire burning like DTS would produce. Nothing wrong with either, I like both. Those are the main differences I've noted...
Also, DTS is compressed if I am not sadly mistaken. It's just not compressed nearly as much as dolby, because DTS has more room for the data, plain and simple. Dolby has a good idea though, fitting everything onto the film. Less to mess with. That's all they were trying to accomplish. In doing so they sacrificed *some* quality, but nothing a consumer would ever be able to tell. We are supposed to know and detect the difference, that's our job. Not theirs... =)
