I think i know the answer, but i'll ask anyway.How do policy trailers play on DTS setups. Will it just drop out to analog like all the non-dts trailers, or does the DTS trailer disk also contain the policy trailers for different theatres? I have heared a DTS drop to analog using an Ultra-Stereo processor, and the audio quality is almost unlistenable. I imagine it will drop to analog when the policy trailer roles through, but I cant fathom that the theatres would allow their policy trailers to be playing in analog.

The Regal Policy trailer DTS codes are not included on Theatrical discs. Come to think of it, I am not sure they have code, don't remembar ever seeing that little green light. They do have a nice sr, dolby digital and sdds output. We also run half of our sound thru Ultra stereos. They do drop out of dts and run in analog (the stereo button on the console). Have your consoles been check on, balanced and such. I believe Dolby processes the signal better than Ultra, but in stand alone the sound should only be a bit less crisp. If your sound levels are low in analog, I would have a tech come out and test and calibrate your system. If your analog does sound that bad , why have you not requested service before. Not all of your trailer could be in DTS, especially not your PSA's.

I don't know about Regal in particular, but I would be surprised if most people making policy trailers go that route (I don't know what DTS charges to include policy trailers on their trailer CDs, but I assume it is not a fixed one-time cost like having SRD or SDDS put on your print would be). But there are usually some policy-type trailers on DTS traier discs. Exactly what seems to vary over time, and does not always match up with what is printed on the dics.For instance, the April 5th dts trailer disc claims to have (according to the artwork): DTS Sonic Landsacpe DTS Digital Experience THX Cavalcade Trl THX Broadway THX Grand THX Tex THX Tex II Kodak Men in White Kodak Million Hours The disc seems to have:
code:
No FILENAME SERIAL TC's MIN:SC:FR Feet.Fr FILE LEN -- -------- ------ ---- --------- ------- -------- 01 dtssonic 735 810 0:27:00 40.08 2,976,750 02 dts 1045 1200 0:40:00 60.00 4,410,000 03 thxbrdwy 15 1140 0:38:00 57.00 4,189,500 04 thxgrand 56 1170 0:39:00 58.08 4,299,750 05 thxtex1 71 1440 0:48:00 72.00 5,292,000 06 tex2moo 257 1230 0:41:00 61.08 4,520,250 07 thxcavtl 1404 1068 0:35:18 53.06 3,924,900 55 menwhtrl 890 1860 1:02:00 93.00 6,835,500 56 kodktst1 914 1890 1:03:00 94.08 6,945,750 57 sil2sec 0 70 0:02:10 3.08 0,257,250
that seems to match up 1:1 ("sil2sec" is on every disc, two seconds of silence). My notes say that these policies have been on past DTS trailer discs:simpsons tex2 cinemtrl cineimax timesliv jbllogo pepsiacd pepsihot pepafi.0 pepaf.0r startrlb wilrog99 I believe "cinemtrl" was a Cinemark policy, but I could certainly be wrong. Incidently, the above formatted list came from "preview.txt" instead of "r14trlr.txt" on the DTS disc. I only recently noticed those on there. Does anyone know when they started being added? I assume it's used by the display on the 6AD, though it seems pretty weird, since all the fields in preview.txt: code:
No FILENAME SERIAL TC's MIN:SC:FR Feet.Fr FILE LEN
can be derived from the fields in r14trlr.txt:
code:
;NAME SERIAL START END OFFSET
--jhawkp.s.: Hey Brad, is there some way to format text in <PRE> in UBB, so tables like the above don't look so bad (other than as an inlined image)?

When it comes to polcy trailers on DTS disks, basically some are on there and some aren't. Unless you can put the disk in your computer like John did, the only way is to try it out and see. Cinemark has had DTS trailers on and off for a while now. Even then, some disks that we THOUGHT were supposed to have them didn't and ones we THOUGHT weren't supposed to did. Like I said, try it and see.Your analog sound shouldn't be THAT bad, compared to digital. You have a problem there, somewhere. Stupid question... apology in advance... When was the last time you cleaned the lens in the sound head? Crappy lenses can lead to REALLY crappy sound. It's an easy thing to forget. Ultra*Stereo processors may not be the best processors (opinions vary) but they aren't THAT bad. Properly calibrated, and with a properly adjusted A-Chain in the projector, you ought to be able to get decent sound out of them. DO call your theatre's technician and tell him the problem. Unless you have some major problem, he should be able to get your sound back to the way it should be in one or two evening's work. It's easy to do if you have the equipment and know-how. You'll be surprised at the difference... Besides, your customers deserve it.
