Brian has a home theater setup with a home theater PC and he's worried that Windows has abandoned the Home Theater PC concept, including Windows Media Center. Leo says that it has been a long time coming since Microsoft has killed Windows home server in favor of Windows 8. Now killing Windows Media Center is just part of that. Microsoft doesn't want to be in the media center business, they want customers to get an XBox One.
What are his options? Leo says there's plenty of third party options including Kodi (XBMC) and Plex. They're still out there and work just fine. There are also Linux versions. Leo says Plex is the best.
That chatroom suggests Media Portal, an open source media center.
