SDL_Window and window manager

Hello all,

I have a little problem with SDL. I use a Linux system with some window
manager (fvwm2, kde…). I wish to open a window (to play a MPEG file
with smpeg) to x,y coordinate but the window manager put my window
elsewhere on the screen! How can I avoid this problem ?? I try to modify
the override_redirect attribute of the XWindow but it seems to do
nothing…

Thanks for you help,–
