A new update/version of the Plex app has arrived in the Windows Phone Store that is a free app but only available for Windows Phone 8 Nokia Lumia devices.
With Plex, you can stream your music, videos and photos from your home computers running Plex Media Server (available from http://www.plexapp.com/) and access content from a wide range of channels. Channels are available for apps like Aperture, iTunes and iPhoto, or online services like YouTube, Vimeo and Revision3. There's also a remote control feature for Plex Media Center.
Additionally, you can sign up for the myPlex service, which lets you connect to servers shared with you by your friends, queue videos from your web browser to watch later, and connect to your Plex Media Server at home wherever you are in the world via Wi-Fi or a celluar connection, with no configuration necessary!
Plex Media Server streams your media directly from your computer, so there's no need to convert before viewing. Plex is smart, too - if your media isn't already in a format your device can play, it'll convert it on-the-fly.
Limitations:
• DRM-protected content (TV shows, movies and older music tracks from the iTunes store) is not supported.
• ISO images are not supported.
• VIDEO_TS folders are not supported.
Server Requirements:
• A Mac running OS X 10.6 or later, a PC running Windows XP or later (Windows Vista or Windows 7 recommended), or an Intel machine running Linux.
So not available for HTC WP devices?
