VLC Media Player is a really powerful multimedia player for Windows. It plays all formats of media files really fast.
VLC Media Player takes only 3 seconds to start and then you only have to select the file and VLC will play it.
It supports MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, ... and DVDs, VCDs, and several stream protocols.
It can also be used as a server to stream in unicast or multicast in IPv4 or IPv6 on a high-bandwidth network.
In addition, it also plays incomplete files, which is really interesting if you are downloading a movie and you want to check if it is the real one or a fake.
All these features have made VLC Media Player (Formerly known as VideoLan Client) one of the most used media players.
It is extremely light and powerful. It's the best multimedia player you can use. It supports all formats and you can watch movies even if they are being downloaded. Amazing!
