I am using MPC-HC from xvidvideo.ru and with internal Gabest spliter (embedded into mpc-hc.exe) I have never observed bugs with presense of tracks or subs in m2ts files.

But - there is one exception.
If you move m2ts-file from BDMV/STREAM folder to some other place and try to open it with MPC-HC - most probably, you will observe the following bugs:
- some tracks or subs are not shown;
- some tracks or subs have wrong language displayed in context menu.
MPC-HC always checks presence of ../BDMV/PLAYLIST/*.mpls data in case of m2ts-file. If these data not found, MPC-HC does wrong decisions regarding content of m2ts-file.

 

Actually, I am not an expert on BD structure.
Let me tell you how I guessed about importance of presence of mpls files.
I had a lot of BDMV folders with remuxes. Basically I played m2ts files in MPC-HC and was quite satisfied with it.
Suppose my movies' catalog structure was like this:

Code (Text):

1. MyMovies
2. |- Terminator      - BDMV – STREAM – 00000.m2ts
3. |                         - ...
4. |                         - ...
5. |- Face Off        - BDMV – STREAM – 00000.m2ts
6. |                         - ...
7. |                         - ...
8. |- Predator        - BDMV – STREAM – 00000.m2ts
9. |                         - ...
10. |                         - ...
11. |- La Vita e Bella - BDMV – STREAM – 00000.m2ts
12.                           - ...
13.                           - ...

One day I decided to remove extra files kept in BDMV folders and leave only m2ts-files (which contain movies). I wanted the following structure:

Code (Text):

1. MyMovies
2. |- Terminator      - Terminator.m2ts
3. |- Face Off        - Face Off.m2ts
4. |- Predator        - Predator.m2ts
5. |- La Vita e Bella - La Vita e Bella.m2ts

But when I opened some single m2ts file (which BDMV extra files I deleted) I realised the bugs with tracks & subs mentioned above.
Then for some particular movie I restored the original BDMV extra files (which I deleted) - and again the corresponding m2ts file played properly in MPC-HC.
Then I again started to delete those BDMV extra files - one by one.
The minimal structure for properly played m2ts file was:

Code (Text):

1. SomeMovie - BDMV - STREAM - 00000.m2ts
2.                  - PLAYLIST - ...some mpls file made by tsMuxer

If delete this mpls file or delete PLAYLIST folder - I observed bugs.

Unfortunately, I am not so fluent in DS-filters .
Could you give me some samples? I will check them on my setup.

 

Sebastiii:

Looks like bug in M2TS splitter.
Use DS mux to remux m2ts in to MKV. It will be working after that.

 

Not all m2ts have this issue - this need to be fixed on splitter side.
You can put subtitles in to MKV in MKV merge.

Of course, we can convert m2ts to mkv:
- first demux m2ts to separate video & audio streams + subtitles (using tsMuxer);
- in case of PGS subtitles - we need to convert them to sub+idx subtitles (using BDSup2Sub);
- next gather everything to one mkv container (using mkvmerge).

But there are 3 difficult issues:
- if m2ts contains PCM track - at demux it will be splitted to several files (each not more than 2 Gb);
- if m2ts contains DolbyTrueHD track - some people could not play it using Haali splitter;
- not all the PGS subs can be easily converted to sub+idx - I mean nice graphical subtitles (with pictures etc).

The main advantage of mkv - possibility to name tracks & subs - like "Voiceover AC3 5.1 (over Spanish)".
But anyway the convert described above takes a lot of time. Also we loose possibility to burn remuxes to BD-disks in future.

So, it is not a good idea to solve the discussed problem by changing a format.

 

So what is the "real" solution (not work around) right now - wait for someone to fix the filters, or?
