<para>If you would like to avoid automatic resizing and always keep the window
the size you make it, turn this option off. &kplayer; will then maintain the
video aspect by constraining the video within the window, as if the window was
maximized for example. You will also want to turn this option off if you get
problems coming back from full screen mode, like endless flickering for example.

choose the one to use for playing video.</para>
<para>Recommended choice depends on the video card you have. If you have a
Matrox card, try XMGA, for other cards either XVidix (if supported) or XVideo
provide the best quality. With NVidia drivers you can also try XVMC output.
If after trying hard you cannot make any of these work, you can use X11
output as the last resort. Video outputs that open a separate window instead
of using &kplayer; video area are not recommended.</para></listitem>
