Dts xd10

Cheers for that. I assume if I am trying to merge two libraries I just do the same but don't delete any of the contents/data files in the copy.

Yes.
Technically the XD10 renews all these files on any boot even if you don't delete them but I had a few times when it got corrupted for any reason, so I highly recommend to delete these files mentionied above as soon the contents folder is manually manipulated.

Hi Michael, how do you get on with say a special event player with a 70mm sound track 7.1 mix and
playing back a 35mm time code eg 2001?

[Michael Zarits]

You want to playback e.g. the 8-channel soundtrack of 2001 using a SpecialVenue-Player and a 2001 35mm timecoded print? Did I get it right?

[Bill Ryan]

Hi Michael,Yes that is correct.

[Michael Zarits]

It depends whether the serial of the 70mm prints matches the serial of the 35mm prints (and therefore if it's the same edit as the 70mm prints). Taking 2001 as an example, the 8-channel DTS (which actually is a 7.0 mix) and the 70mm prints are assigned as SN 20952. Technically a 70mm timecode is the same as a 35mm timecode, the DTS processor does not know whether the timecode is coming from 35, 70 or a generator. However, 5-digit serials at 2xxxx were usually assigned for 70mm/SpecialVenue releases so I would not bet on the compatibility with 35mm prints. If not, I'm confident that serials and timing offsets can be manipulated to run the 8-CH soundtrack with a 35mm print but requires further analysis.

I suggest giving it a try and see. If it's not going into digital you can at least check the serial displayed on the XD10 coming from the print (or just send me a picture of a few frames of timecode and I determine it) and we start investigate/workaround from there.

Basically, the SND file is a typical AUD/AUE file even with the header included. The HDR file is a XD10 specific header containing a timestamp along with regular AUD header data.
Check the header for it's SN at 80-81 [dec(val(80))+dec(val(81))*256], place the file in a separate folder by SN or/and title to prevent multiple files with the same filename when renaming them. Get the reel number at byte 78 [dec(val(78))]. Check byte 92, if it's hex(1) then the file is enrypted (AUE), else decrypted (AUD). Technically you should also check byte 82 for the number of tracks which is 5 for a regular DTS soundtrack. Rename the file accordingly to RxT5.AUD (or AUE if encrypted) and you end up with the original disc without trailers. Btw when it comes to XD10s there is no such thing as merged trailer files, instead each trailer has it's own file like a feature reel, assigned as reel 14.

Depending on the number of files on the HDD this process can be a pain without a script.
So for the sake of preserving as many soundtracks as possible unknowingly hiding on XD10s out there I offer to recover the data of any XD10 HDD back to original DTS-discs to anybody! Just PM me.

Thank you for releasing your work on decoding the metadata files!
I started reverse engineering it myself to write a small program to extract the data of 3 XD10s and recreating the discs, but I was still missing a few things (like knowing how it distinguishes AUE from AUD files). Now it will be much easier to finish it.

I had also an interesting find in one of the HDR files, the title name was not ASCII but Latin-1 (it contained a character that is not valid in plain ASCII).
