Plex is a media player, similar in some ways to Apple's Front Row, but much more powerful. The software automatically organizes movie and television files ripped from DVD's or acquired from other sources and pulls title and plot descriptions from online databases. Plex also integrates with iTunes and iPhoto giving a unified interface for collecting all media (photos, music, and video) in one application. It also supports a number of plugins to pull content from other sources, such as YouTube, TED, or The Daily Show websites.
The new version of Plex, code-named Laika, includes a large number of new features, some of which are covered in this video. One of the largest updates is a new feature called MyPlex, a cloud service that allows easy remote access and sharing of media to other users.
There is also an updated version of the Plex app for iOS. The software allows users to browse media, play video, and control Plex installations, including playing back media on the iPad, including remotely.
