Due to some legal issues in some countries, Ubuntu doesn't come with some great things you would need such as: mp3 playback, Java runtime environment, DVD playback and Flash.

To install all of those just follow those steps:
1) Go to Terminal (Applications > Accessories > Terminal)
2) Type the following command:

sudo apt-get install ubuntu-restricted-extras

or press the following link in order to automatically install the package.
