DTS-HD problems

[Ramscoop]

Trying to demux and encode the DTSMA track from a bluray disc to 1536Kbps DTS.

Using eac3to I receive the error "This audio conversion is not supported." I've had no problem encoding DTSMA until today.

Here is my command line:

eac3to "C:\_Rips\QUACK_D1" 1) 5: "C:\Wall-E.dtsma"
eac3to "C:\Wall-E.dtsma" "C:\Wall-E.dts" -1536

Here is my source:

I ran -test to make sure my ArcSoft DTS encoder was detected and functioning:

The only changes I've made to my system is updating eac3to to 3.18, updating RipBot264 to 1.15.1 (I know RipBot comes packaged with DTSMA decoding features and I wonder if some .dll has been registered incorrectly).

Strangely enough, although eac3to won't demux it, ffdshow will provide playback right from the ripped .m2ts

Any help would be greatly appreciated!

eac3to "C:\Wall-E.dtsma" "C:\Wall-E.dts" -1536

eac3to "C:\Wall-E.dtsma" "C:\Wall-E.dts" -core

I'm not interested in extracting the core DTS track (it is a lower quality source). I want to encode the DTSMA track to a 1536 DTS.

Also, the problem is in the first line (not in the second line):

eac3to "C:\_Rips\QUACK_D1" 1) 5: "C:\Wall-E.dtsma"

eac3to will not work with the track in any way. I even tried:

eac3to "C:\_Rips\QUACK_D1" 1) 5: -demux

but, I always get the same error, "This audio conversion is not supported."

LOL, it's working now.

o_O

I have no idea why it wasn't working before; same script, same source.

*sigh*

I'm not interested in extracting the core DTS track (it is a lower quality source). I want to encode the DTSMA track to a 1536 DTS.

core = dts 1,5 Mbps
Also I would encode to Ac3 640kbps instead of dts. Ac3 is more efficient than dts!

In what way is it lower quality? Is it that you don't want the matrixed centre rear?

Out of curiosity, if you have a matrixed DTS-ES core in a 5.1 DTS MA stream does that imply that the rear centre is also matrixed in the DTS MA stream too?

Must be. The back center is encoded previously in BL-BR and after encode to DTS core + MA extension.

The best option here is extract the core, because:

1) Whit this conversión Ramscoop lose the flag in header than say is a DTS-ES and a receiver with DTS-ES decoder can't know this.

2) Surcode don't encode to 1536 Kb/s (check the output with eac3to and see: 1510kbps).

3) Surcode is a old encoder, maybe a modern encoder can output better quality.

Edit: The bitrate 1509.00 Kb/s is typical of DTS HD Encoder Suite.
The bitrate 1509.75 Kb/s (rounded to 1510 by eac3to) is typical of Surcode
