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

That's where I got the EXAMPLE.
