DTS Express - Demux & Convert from Bluray!!???

[wubba]

I'm currently attempting to backup 'Wrath Of The Titans' to .mkv. Normally in the past with my Bluray's I would delete any PIP video/audio content as TsMuxer would detect the video stream but ignore the audio associated with it (DTS Express; DTS-E). This time I decided to attempt to extract both streams of the PIP content with other software.

I've Googled & Googled, reading forums posts that state the only filter available at this stage for DTS-E is the 'ArcSoft DTS Decoder' which can be used alongside with ClownBD.

With ClownBD+Arcsoft, I've managed to demux the original DTS-E but is unplayable on my system (Win7 x64) even with VLC Player, K-Lite codec pack & the ArcSoft decoder installed. You also have to option to demux & convert the audio automatically to AC3 which is what I want. The conversion is playable but unfortunately it plays x3 times fast sounding like chipmunks on meth!!!. There is a 'FPS' option to 'speedup' or 'slow down' the audio but seems to make no difference!!???
ClownBD + Arcsoft is the only bundle that has allowed me to get this far but I just cant convert the express stream, nor import it into any other program.
Has anyone succeeded in demuxing & converting DTS Express audio with ClownBD or any other software???

Probably NOBODY has found a way to decode DTS Express:

1) outside of a Blu-Ray file-structure ;

2) without the help from a commercial decoder ;

Also, the demuxed DTS-E stream probably lacks a header which is required by the software named StreamPlayer, therefore,...

Look wubba, it's a weekend and we have less participation then. Nobody gets paid to respond to your questions, so take a chill pill.

I did some research yesterday briefly on the subject and I didn't post because I don't have the kind of answer you're going to like and I wanted to see if anyone had anything better to tell you, but since you're impatient...
I found some posts on the subject in 2010 and basically it became possible then to use DTS Express as is, but I don't think anyone was able to change it. At least that is the impression I got from what I found. This was on Doom9 where some of the heavy BD decryption people live. I couldn't find anything more recent.

BD has changed a lot in terms of audio. Although Dolby Lossless is allowed, for some reason DTS won the audio battle in BD. DTS has always had the consumer impression going for it in the DVD days that it was somehow "better" than AC3 so maybe this carried over to BD discs and consumers just assumed that DTS-HD was better than Dolby Lossless. I had never heard of DTS Express until this year. I guess DTS came up with a way to do low bit rate (192 Kbps typically) 2 channel audio for PIP so that the studios could author the whole disc in some DTS format instead of having to resort to AC3 for PIP audio. Disney was using Dolby Lossless a few years ago but they have now switched over entirely to DTS-HD for BD. That's just one example to show you how the industry has changed. DTS has always been more aggressively protected than Dolby's technology and priced higher too, so as a result we've always had fewer tools to deal with DTS. Even the few that exist may not really be legal in some countries as they may violate patents.

Ha Ha!..LOL.. I love it =D Very true... I am impatient & I should take a chill pill!!!

Thankyou so much for your feedback. I've decided to give up on it for now but hopefully in a couple of years more decoders/encoders/DTS-E support will be more common.

Thanks agen for looking into it... If you're willing to provide the links from your research... greatly appreciated Jman98!!!

To anyone who has the same problem as the OP,

now there seems to be a workaround at least:
