I have the 2-drawer DTS unit, so I can't use the DTS trailer disks.

Is it possible to copy the sound files for trailers (either from a regular DTS disk, or from a trailer disk) onto a copy of another DTS disk?

In other words. Let's say I'm playing 3000 Miles to Graceland, which includes the trailer for Driven. Next week I'm playing Traffic, which does not include the Driven trailer. Can I make a copy of the Traffic disks, but include the sound for the Driven trailer from my Graceland disks? (or could I do the same thing but get the Driven soundtrack from a DTS trailer disk?) Assuming the directory structure and everything else on the copied disk is the same, of course.

I know DTS doesn't want a person to copy the disks, but ...would it WORK? I thought this might be a good solution for playing the trailers for some of the big summer movies with films that don't include the proper soundtracks on their own disks.

I really don't know. Perhaps you could have problem with "reel" identification of trailers.
However, try it, and let us know!

I checked the files on one of the disks. There's a file for each reel, and one extra which obviously is for the THX, Sonic Landscape, etc. trailers. I just wonder if the sound for the included "movie" trailers is part of the file for reel 1, or if that sound is in the file with the other miscellaneous stuff.

Apparently nobody else has tried this, maybe I'll do some experimenting when I get some spare time (whatever that is).

On the trailer disc, there is a text file that lists what is in the file. I don't remember if the feature discs have a text file or not. Something to look for, though.

I would think that the trailer is in the R17 file (or whatever reel number they give the trailers). That way they don't have to make a new soundtrack negative for the trailer with a different timecode on it. Unless, of course, the trailer is a different version than previously released.

Why would DTS necessarily have a problem with people burning their own custom trailer discs? It's not like there's any piracy issue - after all, who would want to listen to a soundtrack without any picture? And DTS will continue to produce the feature film discs and presumably be paid by the studios for producing a disc to go with each print, so I can't see there being any loss of revenue.

In fact, rather than put a selection of trailer soundtracks on each feature disc, why not move to a system of making trailer soundtracks downloadable from a website, and providing 'burn-your-own' software to take care of the whole process. You simply launch the program, tell it all the trailers you're going to be playing for the next few weeks, then it automatically downloads the data and burns you a disc with all the soundtracks on.

The only problem I can see with this is the download time involved.

Go ahead and try it. You are legally able to make your own copies for the theatre. It's not like you are denying DTS any profit, but you are actually helping them out by allowing more of their digital sound to be heard. I know DTS movie discs and home CDs can all be copied fine. But I've never tried to mix and match tracks before. Good luck!

Mike -- do let us know if this works. I'd be interested.

The only reason that I might imagine that this wouldn't work (assuming that you copy over all the necessary files to get the system to boot) is that it's possible that the sound files are somehow version-specific to the DTS.EXE program on the disk. The encoding itself is done in hardware, so that shouldn't make a difference, but there might be some subtle differences that (either by intention or accident) somehow make the files non-interchangeable between disks.

I still say that the best solution to this is to add a hard disk to each DTS player, although it probably couldn't easily be made to work as a retrofit for the older models.

Does anyone have a dead DTS unit that I could buy really cheaply? (Slim chance, I know...) I'd love to take one of these things apart and see what's inside it. DTS probably wouldn't appreciate this, however.

Scott, I have heard the older ones are nothing more than a modified 486.

Consider this:

DTS was created long before CD Burners were even remotely popular. There really was no reason (at the time) to include any way to prevent copying the discs or files. This could have been modified with new firmware, however. But seeing as how there is no possible way for this to become rampant and destroy DTS or their profits, I highly doubt anything much has been done.

Try to use an 80 minute CD if possible... that way you can cram even more trailers on!

>>I'd love to take one of these things apart and see what's inside it.<<

The 2-drawer units are 386-based, and the 6D's are 486SX based (I believe the last one I had seen was 25MHz). Also theres 1 or 2 SIMM modules for ram and the SCSI card and two DTS playback hardware cards.

The 6D's I had were all 486 boards/processors. There are internal details in the DTS-6D manual (click below) on pages 19-22 (adobe pages 26-29).

Click below? I don't think your link showed up.

I'm clicking anyway but nothing is happening.

Ah nevermind. You want me to click on MANUALS and then find the DTS manual. Too much work. I am much too lazy.

I compared the file names from two different DTS disk sets.

The file names on the disks are identical. Each disk includes a file for each reel named "r_t5.aud" where you fill in the blank with the reel number.

Then there's another file called "r14t5.aud" which is the sound for the various THX and DTS trailers, circuit policy trailers and the movie trailers.

Each disk contains a text file that tells the contents of that "r14t5.aud" file.

Too bad the trailers aren't in a separate file by themselves or this idea of mine could work. The way it is, if I copied the trailers file from an older movie to a disk set for a newer movie, I would lose the newer trailers because the file names are the same.

I suppose there could be a way of "splicing" the two trailer files together somehow but I'm not that technical. Anyone?

I am probably wrong here but I thought that the text file was the one that told the computer where to look for the filenames of all the sound files on the disk. Therefore if you renamed some of the files and then made a new text file that has the correct filenames in it, you MIGHT get it to work.

I dunno'... I'm guessing.

Assuming on the given feature discs that the attached trailers are on disc A, could you possibly burn the desired trailers on disc B?
