OK! I don't know if I'll call it a bug but all the files encoded with
MPlayer-1.0pre7 show no image with my stand-alone video reader.

I reinstalled thus Mplayer-1.0pre6a which gave no problem and I can't
even see the files encoded with MPlayer.1.0pre7 with MPlayer.1.0pre6a

Thus even incompatibilities between two MPlayer versions or is there a
logical explanation?
