Delay MakeMKV test.

I created with tsMuxeR a Bluray folder adding manualy a delay of 200 ms to a DTS-HD track.
The m2ts output have the delay included:

M2TS, 1 video track, 2 audio tracks, 3 subtitle tracks, 0:02:01, 24p /1.001
1: h264/AVC, 1080p24 /1.001 (16:9)
2: DTS Master Audio, Spanish, 5.1 channels, 16 bits, 48kHz, 200ms
(core: DTS, 5.1 channels, 1509kbps, 48kHz)
3: DTS Master Audio, English, 5.1 channels, 16 bits, 48kHz
(core: DTS, 5.1 channels, 1509kbps, 48kHz)
4: Subtitle (PGS), Spanish
...

I used MakeMKV with defaults and the mkv generated preseve the delay:

MKV, 1 video track, 2 audio tracks, 3 subtitle tracks, 0:02:01, 24p /1.001
1: h264/MVC (right eye), English, 1080p24 /1.001 (16:9)
2: DTS Master Audio, Spanish, 5.1 channels, 16 bits, 48kHz, 200ms
(core: DTS, 5.1 channels, 1509kbps, 48kHz)
"Surround 5.1"
3: DTS Master Audio, English, 5.1 channels, 16 bits, 48kHz
(core: DTS, 5.1 channels, 1509kbps, 48kHz)
"Surround 5.1"
4: Subtitle (PGS), Spanish
...

Then can exist "custom" BD's with positive delay.

When I try to add a negative delay (-200) in tsMuxeR, seems than work like mkvmerge, cut the first DTS frames (verified decoding the track) and add a positive remaining delay:

M2TS, 1 video track, 2 audio tracks, 3 subtitle tracks, 0:02:01, 24p /1.001
1: h264/AVC, 1080p24 /1.001 (16:9)
2: DTS Master Audio, Spanish, 5.1 channels, 16 bits, 48kHz, 2ms
(core: DTS, 5.1 channels, 1509kbps, 48kHz)
...

I don't know if can exist "custom" BD's with negative delay, at least not using tsMuxeR.
