phMAD and mplayer on qnx

I install from the QNX online 3Rd party repository the packages phMAD.qpr
and mplayer too.

When I launch mplayer, it begins to work, i.e. the image of the movie is
bu then it gets cold. The only workaround to see more is to keystroke the
arrow forward 10 seconds. then the next image corresponding to a jump of 10
is displayed. No sound too.

phmad does not work with mp3 also.

Does anybody know howe to fix it ?,
