Well sorry about not noticing bits. Then a correction. The WMV HD is actually
1080p and not 1080i.
I would not call it bit-starved.
It is their certified HD stamped quality. So how can it be their certified
standard and by themselves called insuficient? And i think it should be very
satisfying to most people.
The wmv9 codec is very efficient and smooth running. It includes room for
menues. It is the "Divx of HD films" IMHO.
And wether M. wants it or no,t it will be used as such i think.
It is amazing that they do not want a piece of the cake. Most people have DVD
drives and they are much cheaper than the HDCP restricted DVDR and Blueray.

I think that HD video can look decent at 8-9Mbps, just like regular DVD can look
good at 3.5-4Mbps. It all depends on the quality of the codec used. There's no
reason that HD won't look significantly better than DVD even at only double the
bitrate.

You are so right.:-)
Let the people decide for themselves and download some samples which they can display on their windows PC:
I recommend the former IMAX movies:

R Sweeney talks of "reduced bitrate" as if the 8469 kilobits/sek was a specially reduced bitrate.
If we compare to the default bitrate of Divx on ordinary movies which is 930 kilobits/sec and go after same quality only in HD, then we could say that the square area of HD is about 4X the area of an ordinary film.
So making the same DivX quality in HD as in ordinary DivX we should use about 4000 kilobits/sek!
And Microsoft is using over twice as much bitrate as this default. So are we talking of especially reducement?-No! That is what i will say.
Having experimentet myself with this film:
Elephants dream:

I used 10.000 kilobits(just a round figure) per sec in mpeg4 and there was nothing to complain about. It was abundant. Good quality indeed.
