I had gotten myself all excited about being able to watch Step Into Liquid on my new plasma in HD. Downloaded a few sample clips from the WMV-HD website and they seemed to play just fine on my laptop running on Windows 2000 - absolutely breathtaking. So I ran out and bought the DVD only to find it refuses to play because I'm not running XP. Can someone explain why this is? Any workarounds without having to install XP? The laptop belongs to my company and the IT department is loath to install anything else on it.
