+  <BR>Specially for vidix was implemented video equalizer.
+  <BR>Currently you can use it as command line arguments only.
+  <BR><B>mplayer</B> recognizes and passes to vidix drivers following options:
+  <BR><CODE>-brightness</CODE> - adjust <B>BRIGHTNESS</B> of video output. It's not equal to
+  brightness adjusting on monitor panel or on TV. It changes intensity of RGB
+  components of video signal from black to white screen.
+  <BR><CODE>-contrast</CODE> - adjust <B>CONTRAST</B> of video output.
+  Works in similar manner as brihgtness.
+  <BR><CODE>-saturation</CODE> - adjust <B>SATURATION</B> of video output.
+  You can get grayscaled output with this option.
+  <BR><CODE>-hue</CODE> - adjust <B>HUES</B> of video signal.
+  You can get colored negative of image with this option.
+  <BR><CODE>-red_intense</CODE> - adjust intesity of <B>RED</B> component of video signal.
+  <BR><CODE>-green_intense</CODE> - adjust intesity of <B>GREEN</B> component of video signal.
+  <BR><CODE>-blue_intense</CODE> - adjust intesity of <B>BLUE</B> component of video signal.  
+</P>
+<P>
+  <BR>Each parameter can accept values from <B>-1000</B> to <B>+1000</B>.
+  <BR>Default value for each parameter is <B>0</B>.
+</P>
+<P>
+  <B>Note:</B> Not every driver provides support for each of those parameters.
+  Currently only <B>radeon_vid.so</B> provides full support for video eqalizing.
+  Other drivers only patrly supports these options.
+</P>
