In case URL's are deleted, Google for "TMT3 ArcSoft s Codec Pack".
I used the filestube link.
Password is URL in the "File Description" field.

If someone can point me to the exact installer for 1.1.0.0 then I can make a collective pack out of it which everyone on the forum can easily find.

I can confirm that eac3to downmixes and decodes the DTS-ES 6.1 track from Ghost in the Shell 2: Innocence to stereo FLAC correctly when using 1.1.0.0 (TMT2's final update, rev. 129) and incorrectly (ringing artifacts) when using 1.1.0.7 (my working copy of TMT3, but I've been lazy about updates) and 1.1.0.8 (from TMT5 installer).

v1.1.0.0 comes from the update to v2 that is still on the Arcsoft file servers.

Ok, here's the last update . I finally succeeded doing what I was trying to, here's how:

. First used eac3to to identify how every playlist was chained together using the various evo segments

. Then demuxed video and audio with TsMuxer, manually inputting every single segment for the chosen playlist (no subs since TsMuxer didn't detect them)

. Came back to eac3to to extract subs and chapters

. Converted subs to srt via SupRip. I guess I could have converted them in idx/sub much faster, but since I needed to resync them (yes, on the next step) I went with srt, I wasn't sure if Subtitles Workshop works with idx/sub too

. Subs needed to be resynced with Subtitles Workshop after every "break point" (I don't know how it is called) in the former seamless branching playlist. I guess this makes sense, since they were extracted with eac3to which didn't correctly demux them in the first place.

. Finally, remuxed everything with MkvMerge

A final thought about what could have bothered eac3to so much to prevent it to correctly treat this disc. Forgive if I'm too verbose, but english isn't my language and I have some trouble expressing everything in a better form .

First, I understood why eac3to and every other program I tried to demux the playlists, listed twice as tracks as they should have (subs and audio). It's just that this particular seamless branching is a little more complicated than the usual one, where you have one of the following:

. A shorter and a longer version of the same movie. The short playlist just has to skip the segment of added content. Both use the same soundtrack, so every segment has it and plays it if part of the chosen playlist.

. Two version of the movie featuring alternative versions of some scenes. Robocop comes to my mind for the scene of the killing of Murphy. It's quite close to the first option, there will just be alternative segments for those scenes and the playlist will chose the right one to play. Again, every segment has just one version of the soundtrack.

. Here we have 3 versions. International and domestic fall in the first case scenario: domestic is just shorter than international, so the playlist just chose which segments must be removed from the former. But there's a third version, the 1992 director's cut, which is also shorter than the other two video-wise (first case scenario), but more importantly has a different soundtrack too, since it doesn't feature Harrison's Ford voice over. This of course reflects on the subs as well. So every segment in the disc has to have a soundtrack to be used in international/domestic playlists, and another one for the director's cut playlist.

BTW thanks to everyone who gave me advice, very much appreciated

@madshi: Just wanted to report that eac3to has a problem demuxing subtitles from recent Avatar Extended edition bluray. That disk uses seamless branching if I extract subtitles for the extended edition they still have all the timings from the theatrical (shorter) version.

ArcSoft HD Decoder pack eac3to v1.1.0.0

Latest version: ArcSoft HD Decoder pack eac3to v1.1.0.8

Note: All versions above v1.1.0.0 do not accurately decode 6.1 DTS tracks with eac3to.

[Thunderbolt8]

is there actually anything 1.1.0.8 can do better than 1.1.0.0? otherwise, no other version than 1.1.0.0 would be needed.

I too wonder about this.

I second that wonder.

[Inspector.Gadget]

Well, I guess the thing to do is put together a test suite and run it against all known versions of the Arcsoft decoder. Unfortunately, I don't have a Blu-ray collection large enough to do that.

Known versions of the Arcsoft decoder: 1.1.0.0, 1.1.0.7, 1.1.0.8, ???

DTS Variants: "Regular" DTS in up to 5.1 channels, DTS-ES (Matrix and Discrete) in up to 6.1 channels, DTS 96/24 in up to 5.1 channels, DTS-HD HR in up to 8 channels, DTS-HD MA in up to 8 channels, ???

Or preferably, ask madshi to fix eac3to to work with the new versions.

If my suspicion from looking at the produced WAV file is correct, the new ArcSoft decoder is outputting a record with 8 channels per sample - but of course only 7 of them have correct content.
When eac3to converts it, it treats it as a 7-channel stream, thus cycling data and padding through all the channels ...

[dansrfe]

^that could very well be a possibility, but seeing how madshi has left this and his madVR thread in the dark, I don't know if there will ever be a next version to eac3to.

First, thanks for the easy decoder installation. Every other method I've seen was much more complicated.

Second, when using v1.1.0.8, I only get 6 channel WAV's from a DTS-ES 6.1 track.

Third, how do I go from v1.1.0.8 to v1.1.0.0? I tried just replacing the files, but I get an error "MSVCP71.dll" is missing. Anyone mind helping?

I'm running Windows7 64-bit and needed that file too.
Just google for the filename ... there are a couple zip files out there with the file.

The files I found are slightly newer and still work (but probably have no differences).
All your Mag* files report v1.0.0.148, but there's also a set of 1.0.0.156 out there.
As mentioned earlier, Google for TMT3 codec pack, and you will find it.

As somebody else mentioned, the 1.1.0.0 version needs MSVCP71.DLL whereas the new version doesn't.

Also, I don't think DtsDec.dll is used at all....

True. I think it's from the 2005 redistributable though.

[dansrfe]

yea it uses 2005 redistributable.

Thanks, that helped.

Still wondering though, are you guys getting 7 channel WAV's from DTS-ES Matrix? Or from DTS-ES Discrete? I'm not sure I've ever actually seen a 6.1 Discrete DTS-ES stream.
