No. This is not the lag beween audio and video this is the timestamp 
displayed by smplayer when the video really starts (you have 2 min 
before and 10 min after by default with vdr that I want to cut).

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)

No the one where I removed anything not needed (subtitles, foreign 
language, ...). I have 6 stream when I actually only need two.
So I strip down the ts stream first and then remux.
