[RESOLVED] Audio extracting problem with v2037

I've an extract audio problem.
I've an m2ts file, when analysed with eac3to said there is an AC3/THD audio track, and PCM audio track.
When i create a project and extract audio, i got a .thd file and .pcm file.
If i analyse the .thd file with eac3to, it said that there is only THD audio.
So, problem is instead of the usual .ac3 extracted file, wich contains AC3 and THD, i've a .thd file with only THD.

You can get a sample (first 100MB) of the m2ts file here.

My THD demuxer currently discards the AC3 stream. If you need AC3, then either demux elsewhere, or transcode from the THD.

This is already on my to-do list:

"Demux AC3 from TrueHD"

This is something you've recently changed from previous version ?
Because in the previous projects i've made, the result audio track extracted was a .ac3 file, wich contained both AC3 and THD audio stream. After, with this file, with eac3to, i could extract either AC3 or THD track.
It's the first time i've got only the THD stream in result file. I was very surprised indeed...

It was done as part of the fixes for TrueHD that went into build 2033 (see change log).

Some format conversion "a la" eac3to and playlist gap support could create a killer app. ;)
