Yes, I'm demuxing all the 000xy.ts files in all their
component streams
with ffmpeg for now first, then multiplex the ones I want with mkvmerge.
I might switch to tsMuxeR, maybe also convert back to cleaned-up TS from
MKV also with tsMuxeR to make the smaller recording again playable by
VDR (I've read in the vdr-portal.de forum some users already
experimented with this).
I'm not a codec format spécialist but do individual codec have their
own absolute time stamp? so that you can sync them when multiplexing
them later on? The lag in the TS stream is not constant by any mean at
least on french HD stream, I keeps getting higher and highger if I do
not force to sync them (up to a point it crash the player)
