When Linux is installed, there are no connections to software repositories involving restricted software (such as support for proprietary media technology such as "'''mp3'''", "'''wma'''", "'''avi'''" files, etc... Distributions such as Ubuntu encourage using "open-source" and "non-restrictive" technologies such as "'''ogg'''", "'''thedora'''" files, etc.

If you want to have your system detect this "proprietary" media, which should automatically run the ''Synaptic Package Manager '' to match the most appropriate software to automatically download and install on your system.  (In my own opinion, I think this is truly <u>brilliant</u>, and shows how fast Linux is becoming "user-friendly" to the novice Linux user)...
