As a group we work with partners (my bit) and customers (the other bit). The "other bit" has been working on a number of great consumer focused solutions working with delivery partners such as Fernhart. One of these is the rather nice work with ITN to produce a Vista gadget and a standalone player using WPF.
Download the gadget and access the player from http://itn.co.uk/vista/
NOTE: You can still use the player on Windows XP - but you will need to have the .NET Framework 3.0 installed as well as Media Player 10 or above - see http://itn.co.uk/vista/itn-hub-player/player-faq.html
