mplayer does not work on 9.0pro

Dear list, By chance I tried to compile MPlayer-1.0pre3 on an AMD64 based box running SuSE 9.0 (Pro, commercial one). I noticed a funny behaviour of mplayer on the desktop, that three or four small windows are opened at the top of the desktop without colours; sound seems to be fair. I picked up MPlayer-0.9 or something like that from SuSE8.2beta9 together with libdvdread etc. But, the symthom is the same. Is this a known problem? Where should I look for causes of this problem? Thanks for your attention. yoriaki fujimori
