Because the combined AVC/MVC raw stream of makemvc.exe is not exactly identical to that of combinemvc.exe ...
-- With a sample (CombineMVC.exe + tsMuxeR) Cars2.m2ts :
- It is not readable with StereoscopicPlayer (StereoscopicPlayer recognizes well the format: "separate stream, Left to Right" but no video).
- Remux Cars2.m2ts with mkvtoolnix to mkv (Cars2Mkvtoolnix.mkv) : same effect with StereoscopicPlayer (with default filters) ...
- It is possible to read cars2.m2ts with StereoscopicPlayer by forcing the following filters :


-- With a sample created by MakeMKV SamyMakeMKV.mkv :
- It is readable with StereoscopicPlayer (with default filters).
- Remux SamyMakeMKV.mkv with tsMuxeR in m2ts (SamyTSMuxer.m2ts): The m2ts is not recognized as "separate stream, Left to Right" by StereoscopicPlayer, so that only the left stream is readable (=2D) ...
-- Anything strange, open Cars2Mkvtoolnix.mkv file with MakeMKV :it is recognized correctly !
Record with MakeMKV in Cars2MakeMKV.mkv : it become playable with StereoscopicPlayer !
-- Last note :
Combined MKV (AVC/MVC created by MakeMKV) play with Microsoft DTV/DVD Video Decoder = audio is out of sync.
Tested with MPC-HC.1.6.5.6366.x86 (with Haali Media Splitter, LAV Splitter AND MPC splitter).
MPC-HC report 30fps (with Microsoft DTV/DVD Video Decoder) and audio is out of sync.
It's OK with Haali Media Splitter + MPC video decoder (DXVA or FFmpeg).
It's OK with Haali Media Splitter + CoreAVC 3.01 (DXVA or NOT).
And it is also OK with MPC splitter + MPC video decoder OR CoreAVC 3.01 (DXVA or NOT).
And it is also OK with LAV splitter + MPC video decoder OR CoreAVC OR 3.01 (DXVA or NOT).
By cons, if you remux the MKV with tsMuxer in M2TS, audio is sync ! (with Microsoft DTV/DVD Video Decoder and any splitter).
M2TS files combined AVC/MVC (created by CombineMVC.exe + tsMuxeR) audio is synchronized with the Microsoft DTV decoder / DVD Video Decoder (with any splitter).
if you remux the M2TS with mkvtoolnix in MKV, sound is synchronized with the Microsoft DTV decoder / DVD Video Decoder (with any splitter) !
