I am using the right config and the warnings still show.
Lets prove it...
ps -ef |grep xine
xine --no-gui --no-logo --no-splash -pq -A alsa -f -V xxmc --post vdr --post vdr_video --post tvtime:method=LinearBlend,cheap_mode=1,pulldown=0,use_progressive_frame_flag=1 --config=/home/tv/.xine/config vdr://tmp/vdr-xine/stream#demux:mpeg_pes
So that´s my xine running and shows it is using for config /home/tv/.xine/config
Now I run the grep command on it:
grep "^gui.dropped_frames_warning:0" /home/tv/.xine/config && echo "config is good :)" || echo "config is bad :("
And the result is:
gui.dropped_frames_warning:0 config is good :)
Yet if I open vdr´s OSD and fiddle with it for a minute or so I am guaranteed to get the dropped frames warning.
cxfe does not have the warning problem but unfortunately it does not support xxmc acceleration :(
