If I understand correctly, you think I should do this:
copy /b
i:\VIDEO_TS\VTS_02_1.VOB+i:\VIDEO_TS\VTS_02_2.VOB+i:\VIDEO_TS\VTS_02_3.VOB+i:\VIDEO_TS\VTS_02_4.VOB+i:\VIDEO_TS\VTS_02_5.VOB
You should use "copy /b" if you want to concatenate mpeg streams.
(This is what the command line you provided indicated. If you don't want
to concatenate mpeg streams but produce mkv files, then above is of
course irrelevant for you.)
If you need an mkv file, use ffmpeg -i concat:... ....mkv
Okay, you want me to try that form of concat.
EXAMPLE (from the wiki):
ffmpeg -i "concat:[_input_#1_]|[_input_#2_]|[_input_#3_]" -c copy output.ts
THIS WORKS FOR ME:
ffmpeg -i
"concat:i:\VIDEO_TS\VTS_02_1.VOB|i:\VIDEO_TS\VTS_02_2.VOB|i:\VIDEO_TS\VTS_02_3.VOB|i:\VIDEO_TS\VTS_02_4.VOB|i:\VIDEO_TS\VTS_02_5.VOB"
-c copy n:\output.ts
But I want an MKV, so I'll ignore that the '.ts' above has only 1 audio
stream (which is the Isolated Score track) and I'll change'.ts' to
'.mkv' as you recommend.
C:\CMD & tiny apps\ffmpeg>ffmpeg -i
"concat:i:\VIDEO_TS\VTS_02_1.VOB|i:\VIDEO_TS\VTS_02_2.VOB|i:\VIDEO_TS\VTS_02_3.VOB|i:\VIDEO_TS\VTS_02_4.VOB|i:\VIDEO_TS\VTS_02_5.VOB"
-c copy n:\output.mkv

I am not sure if you already read the wiki article about concatenation
in FFmpeg.
That's where I got the EXAMPLE.
