The PS3 could be worth looking into. How are your music and movies stored on your Mac i.e. what format? If they're in a compatible format (like AAC or MP3 for music and MP4 for videos) you'll be able to stream them to the PS3 using a bit of software called MediaLink. The PS3 also comes with the BBC iPlayer.
