Hi Reinhard, I have undone the offending changeset in xine-lib as per your explanation there. http://sourceforge.net/mailarchive/message.php?msg_name=4A15672E.5090908%40gmx.de Now, zapping time better. What is in your opinion the optimum buffer settings for vdr-xine and for .xine/config ? (I have a Hauppage S2-HD) These are my current settings: vdr/setup.conf xine.modeLiveTV.prebufferFrames = 11 xine.modeLiveTV.prebufferHysteresis = 4 .xine/config # number of audio buffers engine.buffers.audio_num_buffers:460 # number of video buffers engine.buffers.video_num_buffers:250 # number of video frames engine.buffers.video_num_frames:22 _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
