Yahoo bought Meedio last week and has already released the Meedio Pro software ($45) as a free beta. Meedio is similar to Windows Media Centre or FrontRow in that it groups all your media together in a TV friendly format. Yay! for Yahoo! The bad news is that on start-up it checks to make sure you are located in the US using your IP address so will only work for US users. Boo!
However you can get round the US check and run the software although none of the internet functionality will work. I hope you like purple and blue screens.
