There are several HTPC implementations (eg. RaspBMC). They're all pretty nice, but personally, I just use omxplayer, which is the command line package that powers RaspBMC under the hood. It's a command-line-only media player, but it plays anything I can throw at it, including live-streaming 1080p YouTube videos. The command-line interface for omxplayer is a bit verbose, so I wrote a basic wrapper in BASH, so all I need to do is type "play <url>" and the video will begin streaming after a 10-second buffer. I keep a Screen session open on the Pi so I can drop in and command it from anywhere. At any given point, that little Pi can be simultaneously playing 1080p video, while downloading another two videos in the background. Incredibly capable little devices!
