Hi Himashi,
If the picture is too dark when playing XviD movies it is possible to change the brightness setting. Goto the File menu in Windows Media Player and select Properties (make sure that you have a XviD movie loaded or the Properties option will be disabled). Then click the Advanced tab and select the "XviD MPEG-4 Video Decoder", then click Properties. A new window with a brightness slider will be displayed. If you move the slider to the left the picture will become darker. If you move the slider to the right the picture will become brighter. Experiment a bit to find the value that works best for you.
Please note that the above instructions only work in Windows Media Player v6.4. If your system has a newer version of Windows Media Player installed you can still access the older version to make the needed changes. Simply goto the Start menu in Windows, select "Run..." and enter "mplayer2" in the box. Then click the OK button to start Windows Media Player v6.4.
Hope this helps!
