I downloaded the DS3.iso.gz file, but do not know what to use to tare it apart into the files the DTS player wants. I tried burning it onto a CD but the DTS player does not know what to do with it. I tried to open it in my computer, but the computer just askes me what program I want to open it with. Help!

Use WinZip or equivalent to unzip the contents. In there is an "image" file of the DS3 disc. Open up Nero or Adaptec burning software and select to burn the disc "from image". (In Nero this is under the FILE menu.) Then burn away.

Thanks to dts for letting us offer that and to John Hawkinson for creating the image.

I can't unzip it, it tells me that it doesn't appear to be a valid archive, and I should download it again.
I'll give that a go and see what happens.

Nope still doesn't want to know!

What are you using to download the file Pete?

I haven't been able to successfully download a file with Opera without it being corrupted. Internet Explorer seems to work without fail.

Posted by Bruce Hansen (Member # 281) on 07-28-2003, 08:53 PM:

I am getting the same error message. When my download started it said that the file is 47 Megs. The download hit 47 Megs, and kept going to 77 Megs. By the way I am using the microsoft crap.

Why is it G-zipped? Is regular Zip technology not good enough? How big is the file without zipping?

Posted by Dave Macaulay (Member # 813) on 07-28-2003, 10:15 PM:

Well, a CD can hold upwards of 650MB but I haven't been able to uncompress this thing yet either.
It is not, apparently, 47MB. IE gets a file size of 47 when the download starts, and it gets to 99% at 46 and a bit then just stays at 99% while the download continues until 77.3MB at completion.
Windows doesn't know what to do with the gzip file, but suggests a few programs to download.

Is there an MD5 sum for the ISO file included in the compressed archive?

Posted by Joe Redifer (Member # 3) on 07-28-2003, 10:20 PM:

I will try downloading it and posting an uncompressed ISO file.

Posted by Joe Redifer (Member # 3) on 07-28-2003, 10:42 PM:

OK The download was only 47.6 megs as advertised. But after un-gzipping it the file is indeed 77.3 megs.

Download the uncompressed ISO HERE

Then burn to CD with Nero.

PS - I've seen CDs that can hold over 850 Megs. 99 minute CDs hold, well 990 Megs since each minute of music is approximately 10 megs.

Posted by Scott Norwood (Member # 30) on 07-28-2003, 10:48 PM:

Joe--if it holds 99 minutes' worth of music, then it isn't a CD. Just because it is round and shiny and happens to play in some devices which are sold as "CD players" doesn't mean that it conforms to the red book specificiation for the compact disk format. Thus, it can't be guaranteed to play in all players, as many won't play extra-long disks.

gzip is a freely available compression scheme which is designed to be useful on a wide variety of computing platforms.

For those using cdrecord on Unix or Unix-like machines, something like this should work (substitute the SCSI ID of your CD burner and appropriate speed and driver options): cdrecord -v speed=12 dev=0,6,0 driveropts=burnproof -data DS3.iso

Posted by Joe Redifer (Member # 3) on 07-29-2003, 01:49 AM:

Scott - The audio files that burn to the 99 minute CD are the same as those that burn to a 74 minute CD. Very few burners can create them, but most players I've seen will play all 99 minutes without problem, old and new. Actually I have yet to see a player NOT play the 99 minute CDs. No compression. All files are your standard 16-bit stereo 44.1khz audio. By saying it is not a CD, then you must also say that an 80 minute disc is not a CD, since the original spec only allotted 74 minutes.

So yes, it's a CD. Just not one you are used to.

I tried Opera and IE without success, got exactly what Bruce described. I've just set it going on Joes version, so we'll see what happens.

UPDATE:

Joe's version works just fine. Cheers Joe!

Anything that matches the physical properties of the CD is a CD. If it does not match the parameters set down for the Audio-CD, then it is not an Audio-CD in the classical sense, but it still is a CD.

Odd, the file opened just fine for me with WinZip and burned perfectly. I'll do a normal zip file and replace it.

Posted by John Hawkinson (Member # 1135) on 07-29-2003, 10:09 AM:

The issue here is that .gz files are created with the gzip compression utility, which is a standard Unix tool. It uses the same algorithm as .ZIP (PKZIP, etc.) files, but a slightly different file-format. Most, but not all, ZIP software knows how to handle both kind of files. Evidently some people are seeing that corner-case.

As a Unix person, of course I chose the gzip format instead of the ZIP format. But I suppose next time I do this, I'll have more sympathy for the Windows users and just use a .ZIP file. Sorry.

I'll be the first person to ask.

What the phuck is DS3.iso.gz?

Posted by Joe Redifer (Member # 3) on 07-29-2003, 02:21 PM:

I had to open it with a special gzip utility... no problem there. But what seems to be the problem is that the browsers are trying to download it as 77 megs when the file is only 46 megs. If it does that then it doesn't matter what kind of zip utility you have, as the browsers are seeing it wrong (probably have the MIME types for gzip unset).

Micael, this is a DTS that enables your DTS machines to print legal tender for the projectionist every time you play movie.

It's probably my fault that the .gz doesn't work. Knowing that Brad loves Windows and all the lovely Windows software you can buy, I never bothered to configure the http server for non-mainstream windows file types. My bad. [Embarrassed]

Posted by Joe Redifer (Member # 3) on 07-29-2003, 05:18 PM:

It worked for me, Daryl. But then again, I'm on a Mac. Brad's server setup does not apply to me.

Posted by John Hawkinson (Member # 1135) on 07-29-2003, 10:17 PM:

Yeah, the content-type is text/plain. But if you choose "save to disk" in any browser (shift-click, click-and-hold, etc.), it should be fine...

I downloaded the uncompressed file that Joe put on his site. I then opened Nero (disc burner), told it I wanted to burn a CD-ROM, and clicked on new. I then clicked on file, then open. Then directed it to the directory on my hard drive where I had saved DS3.iso. I had to type DS3.iso into the window for it to open (it did not just give me this option). It then let me burn a DTS DS3 disc. It works fine. Thank you to all who made this possible. There is a PDF file on the disc that will tell you about what's on it.
