VLC, the popular open source media player.
Stop worrying about a media file that you couldn't open. VLC can open everything without a hassle.
It's the media player we all love and know!
V. Good for playing DVDs when your PC doesn't have the codecs, as VLC doesn't use codecs apart for saving. Good podcast feature too!
Must perfer this program to Windows Media Player or any of the other video programs out there.
This is truly an excellent software!
