What video player do you used the most for watching video on you computer?  

i cn use different media player i have windows media player classic or vlc media player or Rhythmbox for example i thnk it depens which os i use so wiwndows the first one and other 2 normally linux!!

Same also here, i think most of the files that i downloaded from internet can be played by vlc player, and its so amazing that , it contain all of the codecs needed to play almost any of the file exists in this world, where as in the other media players we need to download add ons, and codecs extra for them, simply wasting our time....isn't it?
