I've been running the Windows 'Whistler' XP beta for about a week now, but can't seem to get Vegas Video 2.0d installed. It tells me that I need Direct X 8, even though I've already installed it. Apart from this, the XP beta runs very well. No problems at all really... well, except that it won't let me install the older Media Player 6.4. I might just get a 3rd party player instead of that.
