Argh, MS support of HD DVD, not BD???

I noticed the announcement of Microsoft’s support for HD DVD ( ). But I am wondering how far this support will go. I had the feeling that the technical superiority and wiser design of BD were perceived by all companies on the host side (hence the many membership in BDA), and that the MS file system team which designed a big part of UDF 2.60 pseudo-overwrite in OSTA public meetings had affinities with BD-R. So I am wondering what are the reason of the MS support of HD DVD, and I am little convinced by the official price argumentation. Opposition to BD-J, the Java-based highly interactive video format of BD? This would be quite silly.


I am highly concern by the potential repetition in HD DVD format of the DVD-ROM, DVD-R, DVD-RW, DVD-RAM incompatibilities nightmare*, even without BD consideration.


*: DVD-ROM, DVD-R/RW and DVD-RAM are all 3 very different physical format specification making that early adopters tend to design drive compatible with only some of the disc, if not just one. Later some manufaturers created ‘super-multi’ devices that supported all types. This is a wicked marketing to design a flaw and them happily claim to solve it. BDA seems to have higher consideration for a intrisec compatibility.
