At any point after you install the software, you can fire up your HD-DVD software and enjoy whatever High-Definition title you choose on HDCP compliant, or non-compliant hardware. After purchasing the XBOX360 HD-DVD drive, I quickly picked up a few movies such as Sahara, Serenity and the Planet Earth Documentary Series. All of these titles are breathtaking and worth purchasing if you've got a display large enough to enjoy them on.
