Using your games console as a media player is not just for PlayStation or X-Box owners, its also possibly with the Wii. You can consume all your media (play music, view photos etc) using your television and your Wii.
As long as you have your Wii connected to the Internet, all you need is to download the Internet Channel from the Wii Shop (costs a couple of quid), and use ORB. Install ORB on your PC (where the media lives) and then browse to ORB online from your Wii. You can then browse your PC’s music collection and photos using your Wii.
I found it a little slow (could be my wireless network), but its usable and a great way to maximise your Wii.
