.AVI or Audio Video Interleave is a video format designed by Microsoft and should be widely accepted in any version of windows media player, otherwise any free .avi player online will do the trick
AVI video files are the most popular video files out there. Any video player will play these including windows media player, VLC media player, PowerDVD, winamp etc.
I'm afraid it can't. You may need a burning software to burn the avi file to DVD first, then you could play it on a DVD player. There is an expection though that some DVD players can play avi. files....
