Good news. The WHS Power Pack 3 will be here shortly and packs a whole bunch of enhancements aimed at Windows 7. The beta has been available for the last couple of months, but this is the official release and will install automagicly if Automatic Updates are enabled on November 24.
Windows 7 and WHS previously didn’t communicate very well, but that will soon change.

Plus, the Power Pack improves Windows Media Center relations with a feature that automatically archives recorded TV in whatever format you want.
