Windows/Mac/Linux: If you've built the media centre of your dreams and download your entertainment, you probably want an easy way to manage it all from another computer. HTPC Manager controls almost every function of your HTPC in one easy-to-use interface.
The great thing about HTPC Manager is that it's free, open source and available on just about every platform. If you're using XBMC as a front-end on your HTPC, Sickbeard to manage your TV shows, Couchpotato for downloads, and Sabnzbd for Usenet, HTPC Manager can handle all of them at the same time. Plus, it gives you a UI that works on any web-connected device, including your tablet or smartphone.
Installing can be a little tricky, but there are detailed instructions to make sure you get everything set up nicely. Once installed, HTPC Manager lets you browse, play and manage all of your media. You can search for new TV shows and movies, view airdates and upcoming show information, and view and manage your active downloads. Plus, since you get a web interface for the whole thing, you can access it from your tablet on the couch, or you can set up your router to let you manage your downloads.
