Microsoft may have thrown in the towel on HD-DVD, but they still believe that HDi which is very similar to Silverlight) is better than BDJ. So Microsoft is making the HD-DVD Emulator available for free. Not only that, but anyone who has already bought it will get a full refund.
Could this mean that Blu-Ray could be seeing HDi support in the near future? If Sony was smart, that answer would be yes... but who knows?
I might have to check this out and report back on the experience... supposedly you can burn it to a regular DVD and use it in an HD-DVD drive...
