Small drift is expected -- the clock used as reference for playback (on dvb/dxr card etc) is not synced to the one used by the broadcaster. It's a similar problem to trying to record audio using one sound card and playing it back using another card in real time -- at some point you will get either over- or underruns because the sample rates are not 100% identical. I suspect some of the issues when playing ongoing recordings just after they are extended are caused by the recorder telling the system to drop the recently written data and this is interfering with the readahead done by the player, which then has to wait for the data to be refetched from disk. O_DIRECT helps here (by not using the cache at all), OTOH it could cause playback problems at the very end (due to the small delay and larger chunks used when extending the file) artur _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
