but I didn't say that!, you should focus very well in my mail, I said that the movie is rendered very well when I comment out the code that render the current frame of the game.

however, I have solved the problem by using glDrawPixels function to render the SDL surface that have the frame from the movie, that will solve the problem if I want to render the movie in fullscreen mode, but when I render the surface to an OpenGL texture and then render the texture to a face from a cube for an example, it will be very slow because I have to create the texture every frame and copy the pixels from the movie surface to the texture to render it as a OpenGL texture and delete it every frame, any one would tell me how I can do it without creating the texture every frame and destroying it every frame in OpenGL.

I think that it should be possible to create the texture once and copy the SDL_Surface to it every frame without deleting it and recreating it every frame.
