There's no reason to touch the audio/video streams at all unless you actually want to re-encode them for some reason. If all you want is an .mkv rather than a .ts, that can be done in seconds with mkvmerge. Re-encoding in that case is pointless & a waste of time. _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
