>You should not use FFmpeg to concat vob files.
I'm not, under Win7
Copy /b VTS_01_1.VOB + VTS_01_2.VOB + VTS_01_3.VOB + VTS_01_4.VOB +
VTS_01_5.VOB dosCAT.VOB

>(You can use it to transcode them.)
That's precisely the issue, I want to use ffmpeg to fix VTS_01_4.VOB which
is jerking, but the transcoding changes the (audio) streams order, so that
I can not concat anymore with the others vob.
