Hi Reinhard,

I have undone the offending changeset in xine-lib as per your  explanation
there.

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
