Dropped frames with xine/xineliboutput + vdr is real problem.
And suppress warning messages is not solution. Dropped frames is 
visible. Sometimes less, sometime more.

This steps little help:
Option "TripleBuffer" "true"  in xorg.conf in Screen section

In xine configuration file:

Disable VSYNC synchronization will reduce CPU usage dramaticaly to 0-8% 
on mpeg2/h264, with small effect to dropped frames:
xvattr -a XV_SYNC_TO_VBLANK -v 0

If you have AMD/integrated graphic, force minimum frequency for scaller 
to 1.8Ghz, it have bandwidth problem:
echo 1800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

During 4 month I was try everything. Over 20 different version of 
xinelib, over 20 version of ffmpeg, 4 different computers. Nothing was 
100% solution.

I was try to create thread on nvnews server, but sometime I thing tha I 
am alone who is able too see this problem.
