Well XP MCE should run that app fine but what I meant was can we get the media center application itself to play these file types. Youre confusing MCE the operating system with Media Center. MCE is basically XP pro with a facelift and a few extras, whereas Media Center is an application that comes with MCE and is basically a front-end for Media Player 10 that allows you to use the remote. I checked that link and VLC dosent support Real files anyway, for the same reason no other player does - its a propriety format owned by Real Networks and they want you to buy/use thier player only. Ok Media Player Classic works but Im not sure if it legally does so!!!
