No, not the application.link API. A web link. Or two.
Some of you may have noticed a new name on the HD DVD Forums of late: Amy Dullard. She also has a great blog that focuses on getting people up-and-running with HDi. Check it out at http://blogs.msdn.com/amyd.
Another person you might recognise from the Forums, Andy Pennell, also has a blog at http://blogs.msdn.com/andypennell/.
And finally, the Microsoft "industry" site for HD DVD is http://www.thisishddvd.com. There's not much there now, but it should get better.
OK, so three links. Four if you count the forums. But who didn't know that already?
The industry website seems way late to the game.
