If you want to embrace open operating systems, quit the Microsoft monopoly or the Apple cult, Ubuntu is one of the most powerful operating systems based on the popular open source Linux kernel. It can do everything that the costly operating systems, only oh so much more, and for free!
The VLC player is your swiss-army media player: it’ll show whatever film you throw it at it, play all your music formats. The multimedia player, streamer and encoder features a huge amount of codecs, translating all manner of formats to your Ubuntu setup.
Since Ubuntu doesn’t come with proprietary codecs, VLC is the first piece of software you’ll want to install on your fresh new Linux box. As one of the first players to offer support to play encrypted DVDs, you can expect this media player to satisfy all your needs now and well into the future.
2. Adobe Flash Player
You’re likely to be using Ubuntu for browsing the web, so one of your first priorities is to download the Flash player as soon as you have your audio/visual software and codecs setup. By default the open source operating system doesn’t come with either Macromedia Flash nor Sun Java JRE support, but the beauty of Ubuntu is that you’ll only have to type a few simple commands in the terminal window to get your web browsing setup properly and fully functioning.
