It's really worth to download and start using MS Player. It's very intuitive and easy to use. After starting use this apps in a Linux (Ubuntu 12.04) environment I no more have messages about missing codecs... I saw in a great quality of image and sound all format videos. And if we want to have subtitles we just asked in the menu to find it online and it’s easy and fast to get (only a few seconds, depending on the web connection) and starts immediately synchronized with the movie/video. AMAZING!!! Today, I start using it on Windows and I highly recommend it to all people, like me, are beginners! Enjoy!
