There are two fairly common reasons why Windows Media Player (WMP) stops to play AVI files. First is that AVI files are no longer associated with WMP. To fix this, open WMP and press Alt to show the menu. From the Tools menu choose Options… In the window that opens, click the File Types tab (note that this doesn’t exist in WMP 12, only in previous versions). Check that Windows video file (.avi) is ticked and, if it isn’t, tick it and click OK.
