What codecs are supported when I creating a video movie screen saver files?

      Power Screensaver Builder uses the Windows Media Control Interface driver to play video movies in screen savers , what codecs are supported by PSSB is depend on What codecs have been installed to your Windows system . That is to say , if you had installed a MPEG-4 codec on your system , you can add a MPEG-4 video movie to your screensaver. Use the Windows Media Control Interface driver to play video movies can reduce the size of output file and can use all codecs on your system.       To check what codecs have been installed on your system , you can click (for XP) "Start" ---->"Setting"----->"Control panel" -----> "Sounds & Audio Devices"---->"Hardware", select the "Video codecs" and click the property page. (These steps may have some difference in different Windows operating system.)
