Helping HD DVD consumers
"One last note this evening: That idea I floated yesterday, that the BDA should offer an olive branch to HD-DVD consumers? I mentioned it to senior BDA executives this evening, and I think you can safely say that they're going to move forward with something along these very lines in the weeks ahead. We'll post more when we can, but the idea was definitely warmly received. In fact, plans are already in the works. We'll post more on this as things develop."

"BD Magic Goes Live
ArcSoft, Inc. and Related Content Database Inc. (RCDB) have come together to create ArcSoft TotalMedia Extreme with BD Magic, an optional Blu-ray player feature that adds both a network content delivery channel and an on-screen personal media library. BD Magic featured players can receive updated Blu-ray trailers, Blu-ray sample scenes, and exclusive high-definition content direct to their Blu-ray player.
The software works by accessing a Gracenote-powered database of 50,000 DVDs and 3.6 million CDs worldwide to make recommendations and promote new related content. BD Magic will be available as a part of the ArcSoft TotalMedia Theatre software."
It seems that it is also possible BD can do DD in the future. I don't think they have to be mutually exclusive.
