mkvtoolnx - Cannot mux a blu-ray playlist with multiple segments of a m2ts

[bokbokchui123]

I have an issue using mkvtoolnx's mkvmerge to mux a BD playlist with multiple segments of a m2ts to a mkv correctly.

From BDInfo, the playlist 00300.mpls info is:

Playlist File Group Length Estimated Size Measured Size
00300.mpls 1 00:46:19 688.00 GB 10.98 GB

It contains the following m2ts segments as follows:

Stream File Index Length Estimated Size Measured Size
01156.mt2s 1 00:01:23 36.21 GB 379.12 MB
01156.mt2s 1 00:04:03 36.21 GB 938.34 MB
01156.mt2s 1 00:03:32 36.21 GB 833.47 MB
01156.mt2s 1 00:01:41 36.21 GB 428.58 MB

When I add the playlist to mkvmerge mux tool. The resulting mkv is very large - 36.21 GB, not the measured size 10.98 GB. The result is the whole movie. It seems it just mux the whole 01156.m2ts, not extracting and merge individual segments of 01156.m2ts.

How can I mux this playlist with correct segments?

Peculiar, I've never knew a playlist on BD could point to parts of m2ts.
You can try if remuxing the playlist with Tsmuxer will yield a better result. If so, you can use that as source to mkvmerge.

Tsmuxer has the same issue. After adding the playlist and demux using ts format, the resulting .ts file is also a big file 36.21 GB.
