This isn't a film review, but it is an analysis on which media player is best for movies when you are watching them on your PC.
Windows Media player and Quicktime suck!
They can't read a lot of formats and they are annoying to use.
I like Mplayer the best since it can read a lot of codecs, but if you can't deal with the user interface I'd recommend VLC.
If you own a Mac, MplayerX is a must-have app.
VLC works well for PC is you want something that is fast and easy to use.
