The Pinnacle ShowCenter is a new entry into the network media devices arena. It looks like a bit of a hybrid system, with a $299 silver box that goes into your home theater setup, acting as a wired/wireless gateway point to your PC's library.
It does music, movies, and images with the added twist of including music and movie ripping into the package. There aren't any thorny piracy questions with this device, as they encourage you to encode your CD and DVD collection for playback from your computer. It's nice to see fair uses of copyright figure largely into a new device, as this is essentially a $300 super CD and DVD changer than can hold as many albums and movies as you have hard drive space for.
