Ubuntu strives to make all software that meets the licensing terms in the [WWW] Ubuntu License Policy available. However patent and copyright restrictions complicate free operating systems distributing software to support proprietary formats.

Ubuntu's commitment to only include completely free software by default means that proprietary media formats are not configured 'out of the box'.

Ubuntu can play the most popular non-free media formats, including DVD, MP3, Quicktime, Windows Media, and more by following the instructions below. If this seems like unnecessary work, remember that Ubuntu is a distribution of free software and these packages are (at least arguably) affected by patents and license restrictions in some countries. Avoid formats suppressed by DRM (Digital Rights Management, or Digital Restrictions Management), as they are often unplayable.
