Plex has this week launched a new channel on Roku which now allows Plex media users to view their content from a Ruko player. The new channel now makes it possible to share videos stored on a computer using Plex from your Roku media player, and play back Internet video from a number of sources.
Be aware though that Roku users still require the Plex media server to be running on their computers. The Plex media server comes bundles with the Mac OS X version of Plex, and Windows users can download a standalone server application.
For more information on Ruko media player jump over to their website.
