VLC is nice for files I can't get to play in windows media player, though that rarely happens. The only type of files that I can't get to play on my WMP are .ogg files and .mkv files. Other than that, I'm updated on the codec pack, so WMP can play most file types. The only thing holding me back from using VLC all the time is the interface, no library like WMP and it's just a simple ass player really.....
