how - DTS audio with DVD Arch 2.x?

[dex Otaku]

I am attempting to make a DVD of my own material that includes 5.1 surround soundtracks. The AC3 version works flawlessly, as does the separately-mixed PCM stereo track.

Another [old] post here said that tracks encoded to DTS WAV with Surcode DVD should work with DVD Architect. This does not work for me, however.

Software decoding of the tracks once written results in the expected white noise of an invalid stream being decoded as straight PCM.

Hardware encoding simply does not work at all; the decoder acts as if no stream is reaching it at all. [AC3 and actual PCM work fine]


DVD Architect sees the Surcode-created DTS wave files as 44.1kHz/16-bit PCM. Since the track is actually 48kHz audio, should this be saying it's 48kHz PCM instead? Perhaps the data is being read/sent at the wrong rate, which is why the hardware decoder is seeing nothing at all.

I have tried throwing padded and unpadded dts files at the DTS2WAV utility [most recent version asof this date], but it just crashes, producing a corrupt file that DVD Architect doesn't recognise as being anything at all.

If anyone has any suggestions on how to make DTS work with DVD Architect 2.x, I'd love to hear them. The project I'm trying to finish up [after almost 2 years] is a 5.1-surround radio drama engineered from scratch with Vegas, and I'd much rather hear it in DTS than Dolby Digital.

Thanks all,
D.

Correction:
The DTS Wave files -are- seen as 48kHz, not 44.1, so the rate should be correct.

I can understand that this is undoubtedly a fairly obscure topic.

Perhaps I have posted this in the wrong forum? Would it help to put it elsewhere?

I'm not expecting an instantaneous response with a solution [having used fora and newsgroups since around 1990, I know better than this] but even if you don't have an answer to my problem - does anyone have advice on where might be a more appropriate place to ask? Or directions to elsewhere that might have this information?

Thanks much,
D.

Having finally and fully realised what's going on:

Yes, you can hand DVD Architect 2 a DTS stream with a WAV header, and yes, that will apparently decode on set-top players with audio routed digitally to a DTS decoder.

This coesn't work from my computer, however, as my sound card's drivers do not permit proper SPDIF output of DTS [except through one single piece of software; PowerDVD does it just fine, but then, they liscensed stuff from DTS, so they can probably encapsulate the stream correctly, unlike VLC, Foobar200, &c.].

In the end there is only one thing to note:

You can't do fully-compliant DTS audio from DVD Architect, period.

Your 'cheapest' option, in terms of software, for multiplexing spec-compliant DTS-audio DVD Titles would probably be DVD SP 3, but you'd need Mac hardware to run it on, unfortunately. Mind you, a Mac mini will only set you back $500, so it's not all Doom(9) and gloom! ;)

DTS muxing was reintroduced in version 3 of DVD SP, since it was removed on the original 'migration' of the Maestro codeset to the Mac (under the guise of DVD SP 2).
