Yes, I am talking about the dvb subtitles. Here the subtitles are in sync when watching live. But when I try to watch a recording I get the subtitles 6 seconds too early. If I understood it correctly the reason for this is known. This explains the reason: http://www.linuxtv.org/pipermail/vdr/2008-October/018072.html but not the cure :)
