As you may know, Netflix does not work on Linux. But do not worry, there are some tweaks that can be done for you to watch movies on Netflix.
The Netflix-desktop package contains open source packages including Wine customized to run Netflix, Microsoft’s Silverlight browser plugin, needed by Netflix. This works on Ubuntu 13.04, 12.10, 12.04, but it works better for Mac OS X or Windows.
This is how you install Netflix-Desktop on Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal and Ubuntu 12.04 Precise Pangolin.
This is what you have to do:
$ sudo apt-add-repository ppa:ehoover/compholio
$ sudo apt-get update
$ sudo apt-get install netflix-desktop
If you want to remove Netflix-Desktop, do:
$ sudo apt-get purge netflix-desktop
$ sudo apt-get autoremove
$ sudo apt-add-repository --remove ppa:ehoover/compholio
$ rm -rf .wine-browser/
