Ah. A unadorned soatrfwe problem needing a quick solution. Yes, there are some file formats can't handle such as that of .avi format, for example but don't fret straightforwardly over something you terribly need playing when you can get another program to compliment your record woes. Try VLC MEDIA PLAYER from download.com/filehippo.com Its hailed as a player that plays all record/audio universal formats on the glide, be it .wmv, .avi, .mpeg and etc . Entrust me, I never had to look at any additional media player again after using it. You won't believe this except you download this straight away. Guaranteed.
