SDDS Stream

[BilyMar]

I have a problem ... I have ripped two Audio Streams with the SmartRipper .. and now: DVD2AVI only demuxes the AC3 track ... and I want the SDDS Audio Stream aswell, but i cannot do it .... does anybody know what to do??
PLZ help me!!
m.f.G.

You said you used SmartRipper to get the audio streams? Then why do you need DVD2AVI at all? SmartRipper can demux the streams just as easily by checking Enable Stream Processing and setting the SDDS track to "Demux to extra file".

[BilyMar]

oh ... I've never heard that before .... now the problem is, that I havent the DVD any longer, but I have the Vob Files with the Stream on my HD .... is there any possible way to get it??

@ Bily Mar
1) I never heard about DVDs having SDDS, never!
2) What the hell do you want to do with a crappy SDDS-Stream?
3) Stick to the Dolby Digital stream and be happy that you have tools that can decode it!

[BilyMar]

Tomb Raider has a SDDS Stream .... it has two ac3 streams and one SDDS stream ... (in the german language) .... su I streamed the english ac3 and the german SDDS ... but i cannot demux the SDDS with DVD2AVI, and I dont have the DVD anylonger .. so please tell me how can I get the Audio from the SDDS into a single file??
AHHHHHHHHHHHHH

@BilyMar:

I don't think there is any way to get an audio stream from the vobs once they are already on your HD....at least I've never heard of one. But I could be wrong of course.
BeSweet can use vobs as input but of course it can't decode SDDS.

@Bobotns:

Crappy SDDS? SDDS is a LOT better than Dolby Digital even! It has up to 8 channels and a higher possible bitrate, so it's far from crappy. Unfortunately you are correct that you can't do anything with it. It's a purely theatrical audio format, so unless you have special equipment that can decode it you won't be able to play it. Much less convert it.

In my opinion it's quite useless for ripping a DVD movie to CD's, so you might as well just stick with the AC3.

@ Acaila
That's exactly what I ment with crappy. You can't do anything with it and it's a dying format ;) exactly like that DTS piece of shit, when it comes to bitrate, even Dolby Digital can go up to 640kbps! so argumenting that DTS has lower compression is senseless...
So let us stick to Dolby, a widely used format, doesn't consume that much bitrate, offers excellent quality and one can use it in 2-CD rips without carrying too much about the picture quality ;)

LOL:D If you say so bobotns.

Yes, but I have yet to see a DVD with a 640kbps AC3 stream.
DTS does up to 1.5Mbps.

Not that I like DTS (in fact I fucking hate DTS because there are no free software decoders available), but it does sound better IMO.

@BilyMar
Bbdmux might be able to demux the SDDS track but I don't know what you would do with it once you have demuxed it.

Same here. In fact I doubt they even exist, at least for NTSC.

As more and more DVD's come out with DTS then I suspect we might see a soft decoder eventually. It's all about the demand. Depending on the DVD, clearly DTS offers far better quality. Unfortunately, some of the DTS movies that are coming out are stupid canidates(ie. non-action flicks)

Indeed, but 768kbps(DTS) > 448kbps(AC3).

you mentioned 'there are no FREE dts software decoders'

what software (free or not) could i use to decode this DTS file i have??

[Doom9]

umm.. I guess you're refering to this DVD: http://www.amazon.de/exec/obidos/ASIN/B00005NFL7/ref=ed_ec_h_cs_2_1/028-6059487-7641365

It clearly says.. DD and DTS. Many rippers wrongfully show DTS tracks as SDDS. There is no SDDS on any DVD I would know of. There would be no player capable of playing this format or receiver capable of decoding this format.

WinDVD and PowerDVD are the only programs that I know of that are capable of decoding DTS. But DTS decoding only seems to work while playing DVDs. I have tried to get a decoded DTS stream out of the WinDVD filter "iviaudio.ax" in graphedit, but whenever I load a vob file that has DTS the audio output of the filter is disabled). There might be some way to hack it ... I mean there must be some way to intercept the decoded audio output of these players before it is sent to the soundcard.

There are plenty of hardware DTS decoders available but they cost $$$$.

[DJ Bobo]

I wanna say something: the DVD publishers are making some sort of hype about DTS, as it was the non plus ultra sound standard. I see it as an argument to own 2 times more money, with a "normal" DD version, and a "deluxe" DTS version.
As people say here, I wanna see a DVD with Dolby Digital @640kbps, so we can really compare between DTS & DD.
I don't even understand how DVD authors can put 384kbps DD streams. This is absurd, especially with a movie like "the Matrix", 384kbps doesn't allow frequencies over 18KHz. The sound is not dynamic enough with such a low bitrate.
With 448kbps, DD begins to show its true power (full bandwidth up to 20KHz). And with 512kbps it may kick the ass of that DTS piece of shit. If not then it will do it for sure with 640kbps!

And you'll never see DTS @1536kbps, since this will decrease picture quality dramatically! (even 768kbps is too high in my opinion)

So I'll stay to my word: DD is better than DTS!

How do you make such bold statements? If you have ever watched a SuperBit DVD, watched Pitch Black DTS,U-571 DTS, etc then you would know that the DTS track is clearly more full and rich. What do you base a general statement like this on "DD is better than DTS"?

Someone please name one DVD that has a cleaner and richer DD track compared to a DTS:rolleyes:

@ Matter
And I know that DTS sounds better than DD, but it is because in all comparisons I saw in the Internet, DTS is compared to DD @448kbps and even @384kbps and then come at the end and say: hey, DTS sounds clearly better! of course, it sounds better!

Well, I'll never compare MP3 @192kbps and Dolby Digital @384kbps, and then come with the result that Dolby Digital sounds better, because it's obvious.
That's exactly what people are doing, comparing DD and DTS with almost the double bitrate!

They gotta compare DD @640kbps and DTS @768kbps and then come with a result!

[MaTTeR]

So why do you call DTS crap then if you know it sounds better? I don't understand.

I understand what your talking about in regards to the comparisons though. The problem is I've yet to see a DVD with DD 640kbps. So how are they suppose to compare? If I were guessing I'd say the DTS encoding hardware is superior to that of DD. This could be the reason were seeing sub-standard DD DVD's.

[DJ Bobo]

@ Matter
I called DTS crap, because it consumes too much bitrate, and the quality is not significantly better than DD @448kbps.
I consider the DTS track as space and bitrate wasting standard, as DVDs *must* have DD tracks. So why not just make the bitrate of the DD track higher instead of wasting a bunch of 768kbps to get a DTS logo on the cover?! that could make picture quality even better! but well, we couldn't do much about that, the companies do what they want anyway so I'll stop here.
I just wanted to tell my opinion about all that...
