I picked this post from the Rio World site.
Microsoft have launched a new tool for portable audio devices in Windows XP. Although this is part of the Plus! Digital Media Edition pack, the Power Toy is available to download free of charge.
The Power Toy gives you a My Audio Devices entry in My Computer, under which supported portables appear. When you open them you get a Windows Explorer style view of the portable content, including metadata such as title and artist. You can load content onto the portable simply with drag & drop or cut & paste from your hard drive.
We have worked with MS for the last few months to ensure that the Power Toy is supported on most of our products, including the Rio Riot. The download URL for the drivers at sonicblue.com is provided on the Microsoft page.
Start at:
http://www.microsoft.com/windows/plus/dme/mehome.asp
The click the Power Toy link near the bottom of the page to download the toy and find the links for the SONICblue drivers. Don't forget, this is XP only.
Enjoy!
The link doesn't work so try this one:

I downloaded the tool and drivers but haven't tryed it out yet, but I figured I'd pass it along.
