Click on the first drop down menu and select, "Microsoft." In the second drop down menu select "WMV 2 Generic." With these options selected, click on the button labeled, "...," and select where you want your converted videos to be saved. The only thing left to do now is to click on the, "convert" button. After you do this, an MS DOS window will appear and show the progress of the conversion. When it is finished, it will display the message, "Press any key to continue." At that point, press any key on the keyboard, and it will close the MS DOS window. You can then close the WinFF program.
