Well,
Hello all (again!). I've tried to do some DTS disc copies via Adaptec Easy cd Creator 3 and it works just fine as Easy Cd Creator 4. So I don't think you will have a problem with this. BUT. When we used the copies in our theater the DTS dropped out occasionally for two or three seconds and then returned to DTS again even though no TIMECODE was lost. Did this happen to anyone else? What do you think the reason is? Could it be bad copies? I know that DTS supposedly should not be receiving Timecode for some seconds to drop out to analog but DTS has been receiving Timecode throughout the show. It happened in both times I tried coppies on different films. We use changeover with two Victoria 5 projectors, Dolby CP65, DTS 6D unit and stereo sollar cells on the projectors.
See ya guys

I have made several backup copies of DTS disks:

1) I backed up all my test disks so I can work from the copies and keep the originals from being damaged from everyday wear and tear.

2) A couple of theatres needed an extra disk because they didn't get one with a print or the ones they had got scratched up.

I have never had a problem copying them with "Toast". I just put both disks in and go. I've never thought much about it, really. It just "works".

I wouldn't think twice about copying a DTS disk. You have to have the print and a DTS player to make it work. If anybody gave me any trouble I'd just ask them, "So... you don't want me to copy the disk, you won't send me another set of disks and you STILL want the movie to play in digital?"

First thing, thanks for all the suggestions. I posted this late last night and was suprised at how many responses this topic received just by early morning.

As far as CD dropouts go, I wonder if that is not something to do with the speed of the CD-R recording versus the speed of the CD-ROM drives in the DTS unit. The original DTS-6 2-drive units had 2X SCSI Toshiba drives (pretty dang slow). I would guess any CD burned at 8X to 16X might be prone to have problems on playback. I don't know the rated drive speed on the DTS-6D units (my guess is 4X or 8X), and those are the models that will be playing the dubbed discs.

Anyway, I am tempted to burn the discs at a slower speed (like 4X) just in case. Carmike's district manager is going to be in town for the weekend to see how things go with the competition's new opening. I certainly don't want the CD-Rs dropping out audio with any of the big bosses around.

A lot of things have been going on over at the Carmike theater to get appearances polished (some new bulbs, sound systems tuned up, screens cleaned, odd items like a replacement cup holder here and repairs on a door handle there, and --oh yay!-- that 8th DTS system will likely be installed within the next week or two, and the Carmike theater in nearby Duncan is finally getting a full DTS sound system package of their own). The fellow that owns the property on which the theater sits is spending $6000 of his own money to promote the Carmike theater. The caption "DTS Digital Sound Equipped in all Theatres" is certain to come up in future ads. If the paper needs a polished EPS vector file of that snazzy "Digital Experience" logo, I got it.

In another subject area, someone was asking about "Okies". One thing that is true about a lot of Okies around here is that they are getting increasingly sophisticated in their movie going knowledge. With all the DTS and THX trailers playing at the theater and the DVDs with those DTS Digital Surround banners on shelves at the video store, audiences around here know what DTS adds to the movie going experience.

Unless you plan on burning a buttload of CDs, 4x-6x should be fine. The speed really doesn't matter too much, as some of my DTS units have 16x drives, and others 32x drives (just depends on what we replaced the original Toshibas with). They all work fine.

This entire problem would be nonexistant if DTS would just set up a server with the movie sound on them, and then stream the audio to each theater. A surcharge of 12.5 cents per ticket could then go to DTS. Oh wait, that sounds like an incredibly dumb idea, doesn't it?

On the subject on interlocking Pearl, I got a note saying that Disney did not want the prints interlocked. Does this make sense? Did anyone else hear this?

Apparently Disney thinks that interlocking a print will damage it. Guess they must've been scared by the Interlocking video (which by the way did not put the slightest mark on that print!)

I dupe dts cd-roms at 8x and have had zero dropouts. I think the bottom line is whether you have a good burner or not. I used to have a HP and it was a piece of . I now have the TDK burner and it was well worth the money!

Right - I've heard that the TDK burner is excellent despite the slightly higher asking price. However, (as with all products) there are two types of burners...and one of them is the type that works.

For those in the market for CD burners, check out the Plextor SCSI units. I've heard nothing but good things about the Plextor drives, and I will probably buy one of them as soon as I convince myself that I need a CD burner.

I have used many CD burners in varying configurations, the Plextors are deffinatly at the top of their list, They are a higher priced (particularly the SCSI units) but well worth it. TDK's follow suit right after them. Basically if you get one that has "burn proof" you should be ok, as they have a larger buffer to prevent the infamous "buffer underrun" errors.

I find that the CD burners made by Yamaha to be prety good. (OTOH) I had an HP unit that was nothing but trouble.

Well, the CD-R copies worked! I ran them off using the CD Copier utility, and as Joe Redifer suggested, I checked the "copy CD to hard disc" item under the "advanced" tab for making the copies. I ran them off at 8X, which had all four discs copied without any snags in about 40 minutes. Afterward, I checked the file and directory structure between the original DTS CD-ROMs to verify all copied files were identical in size (that way I would know for sure the data was not changed in any way). Pretty nice.

The DTS mix was pretty good too. Lots of aggressive split surround use, particularly with bullet hits and airplane fly-by effects. Nice picture quality too. I was pleased to see the 2.35:1 image photographed anamorphically instead of the Super35 stuff that just doesn't look as good. So what if it has to be severely panned and scanned on video? I buy and rent DVDs instead anyway so I don't care about "home video safe" widescreen.

Thanks for all the help, guys.

If I were burning a DTS disc, I would only burn it at 1X. Anythiung else (2X, 4X, 8X etc...) could damage the laser in the DTS Unit due to bad quality. It may burn faster at 16X than 1X, but I can guarantee you, you fry your unit.

How's that? DTS units use standard, everyday computer CD-ROM drives (SCSI). If they don't fry your home unit they should be fine in a DTS player.

Kyle you are incorrect the laser will have no detrimental effect due to burning speed.
The only problem is if burned faster than 2x the old caddy style toshibas will tend to have high errors.
It is virtually impossible to burn a CD that will damage a playback unit

Hello Bobby,

The discs to not belong to DTS, they belong to the studio. They are CD-ROMs, not "regular" CDs. As you all probably know, copying CD-ROMs is very easy if you have the correct hardware. If you choose to do it, I don't want to know (hint hint).

If you ever need discs, please try the film distribuator first and if they don't have any, then email me and I'll try my best to get you another set ASAP.

Karen at DTS
