Game Theatre XP dvd DTS/ Digital Decoding

[VERT]

Just brought one of the cool soundcards, has anyone managed to get it to do dvd DTS/ Digital decoding? I have read on the Hercules Forums that this cant be done, but hang on wait a minute the card clearly states that it does 5.1/AC3, so what would be the point of this then?
please give me any info you have regarding this as this was one of the reasons I got this sound card.
Cheers

From my understanding 5.1 and AC3 are Dolby formats. DTS is something different.
It should be able to do the 5.1 and AC3 but I would not bet on the DTS.

You refer to Dolby? are you talking about Dobly prologic or Dolby Digital, because dolby digital is like DTS and is oftern referred to as AC3 and 5.1, but prologic is something different.
On the box of the GTXP it says that it will do Dobly Digital, but what I want to know is

has anyone managed to get it to do dvd DTS/ Digital decoding?

well as I have just found out this card does not do DTS/Digital dvd decoding, a bit silly really when tells you it is a Dolby Digital/ 5.1 card.....

Dolby digital=ac3/Dolby 5.1.
Dolby prologic=dolby 2.0.
The numbers referring to channels.
If it has 5.1 output, then it can output dolby digital sound.
Dolby digital is a lot like dts, but it isn't the same at all. If you have dolby digital decoder and the sound stream is in dts, then there's nothing you can do.
Often dvd's that are dts encoded, have also dolby track.

I know this already as I have a Dolby digital/dts setup

prologic (4.1)is not 2 channels as you say but rather a Front left, a front Right a centre and a mono rear channel and sub (.1)

Digital/DTS (5.1)is similar except there are 2 rear channels (stereo)

however my original question was

has anyone managed to get it to do dvd DTS/ Digital decoding?

but I have now found out with the current software and drivers that this is not possible.

I hope this clears up the confusion between AC3 and DTS. Source: http://www.sel.sony.com/SEL/service/dvdplyr.shtml#s4
5.1 is a generic description of a multi-channel sound system. All of these surround sound types use 5.1 channel decoding to provide surround sound. The 5.1 channels are as follows:
Left Front
Right Front
Center Channel
Left Rear
Right Rear
LFE (Subwoofer)
AC3 is a compression technology term, which is used in place of Dolby Digital. It is essentially Dolby Digital.

Dolby Digital surround sound is compressed which allows more audio information to fit on a DVD disc.

DTS surround sound is an alternate 5.1 surround sound which DTS states is not as compressed as Dolby Digital.

In my view, DTS DVDs sound better than AC3 ones.

Actually you're wrong, dolby prologic is just stereo audio. The remaining channels, center and surround are mixed derived from the main channels. And there is no real subwoofer support.

By this time you got my interests up http://www.sysopt.com/forum/smile.gif
Seems you were right too, http://www.dolby.com/tm/surround.html

As for the original question, I don't know. I have aureal vortex superquad digital, and it can't even output the 4-channels its supposed to create throught the digital http://www.sysopt.com/forum/smile.gif
