When I played an .avi file on WMP9, I was told that the file has an
extension that did not match the format and did I want to proceed -yes or
no. On one occassion I said 'no' and now most .avi files just won't play.
Does anyone know how I can revert the player to 'yes' so it can play. On
the files that won't play, I've tried it on another machine and it plays
fine.

TIA

Go into "tools" then "options" then "file types"....check off .avi...

Right-click an AVI file in an Explorer window and choose
'Open with>Choose program'. Now select Windows Media
Player from the list that appears and check the box "Always use
this program open these files".
