I wanted to know if this problem is the same one which occurs with a
standalone application based upon libvlc too.
Indeed I am building a video player (with libvlc 0.8.6c on Win XP,
multiple instances of player simultaneously playing, audio or video) and
I have similar problems.
For example, changing the current playing item (using
libvlc_playlist_play) frequently causes a crash or an abnormal and
unpredictable behaviour (the subsequent libvlc functions calls does not
work normally).

Is the "Known bug" identified by JB Kempf being processed by libvlc
developer team ?
What advice can you give me ?

Thank you in advance for any help,
Chris B.
