This list is fine. Please follow the guidelines described here:

I need to be able to reproduce what happens on your machine. Also,
 which TAP 
plugin do you use? (the TAP-plugins is a collection of several
 plugins).

Thank you for the pointer.  The bug report is filed here:  http://bugzilla.mplayerhq.hu/show_bug.cgi?id=957

This is a pitch shift filter.  In that report, I also mention a problem when there are 2 audio tracks, the filter doesn't work with the 2nd track when switch track on the fly by users, or when switch the track back to the old track, the audio will be reset to normal pitch (unless there's something I miss here).

The command I use is:

mplayer -af ladspa=tap_pitch:tap_pitch:0:0:-90:0 -fs -fixed-vo -vf yadif=3:1 -slave -quiet -noborder -brightness 0  somevideo.mpg

or with pitch shifted:
mplayer -af ladspa=tap_pitch:tap_pitch:5:0:-90:0 -fs -fixed-vo -vf yadif=3:1 -slave -quiet -noborder -brightness 0 somevideo.mpg

If you can't reproduce the problem, I'll find a way to submit the video to you.  Thanks.
