Simple Directmedia Layer

I use C++ and SDL to make a 2D Sidescroller Game.
But I have problems with the "Tearing", it looks fucking ugly when move sprites.
I already activated "SDL_DOUBLEBUF" and "SDL_FULLSCREEN".
I also switched "Doublebuffering" on, at my graphics card configs.
I even tried "SDL_SWSURFACE"(software renderer) instead of "SDL_HWSURFACE"(hardware renderer).
And of cource I use SDL_Flip instead of SDL_Update.

What am I doing wrong?

hw_available IS 0
    Is it possible to create hardware surfaces?
wm_available IS 1
    Is there a window manager available
blit_hw IS 0
    Are hardware to hardware blits accelerated?
blit_hw_CC IS 0
    Are hardware to hardware colorkey blits accelerated?
blit_hw_A IS 0
    Are hardware to hardware alpha blits accelerated?
blit_sw IS 0
    Are software to hardware blits accelerated?
blit_sw_CC IS 0
    Are software to hardware colorkey blits accelerated?
blit_sw_A IS 0
    Are software to hardware alpha blits accelerated?
blit_fill IS 0

video_mem IS 0
    Total amount of video memory in Kilobytes
vfmt (would take too long)
