If you love having access to your media on your mobile device like I do, you need to check out Plex. Movies, TV and music all go wherever you have internet access. And depending on how much internal storage you have on your device being able to stream some can make a big difference in how often you have hook your device up to your PC. Plex makes accessing all your content a breeze. Just setup the server software on your PC (Windows, Linux, Mac and even some NAS appliances supported) and grab an app for your mobile device (Android, iOS and even Windows Phone 7 and 8!) and you’re off! Plex will handle transcoding on the fly if the media format isn’t supported on your mobile device.
Some of the features I’ve really started to enjoy is that Plex knows which items from your library you’ve watched and then marks them as such. So when I want to check out something “new” I can easily find that content. Plex also will allow you to “Sync” content to a device and does so brilliantly. The Plex server is free to use, but for supporters there are a lot of extra features are unlocked with the “PlexPass” subscription.
I’ve used a lot of different UPnP streaming servers and NONE have performed as well as Plex. Check it out. Plex is supported on a bunch of different devices and is worth every penny for the extra features if you decide to go that route.
