One of the coolest features (well reasonably cool but practical) features of Windows Media Center is the ability to go to MSN TV and remotely set programs to record.
Unfortunately it’s not available in the UK (in fact I don’t think it’s available outside of North America). There is a less than ideal workaround though. You can run Media Center through remote access. You can’t play videos but the interface works well enough to set programs to record.
I’m assuming it will be available in other countries eventually.
