I downloaded the Windows Media 9 HDTV 720p sample clips as I was interested in seeing what their quality is like compared with a satellite HDTV channel I get "Euro 1080". While WM9 definitely does look a lot more detailed than DVD, it does not do a good job at smooth scenes such as calm water and sky. For example, have a look at the clip "The Magic of Flight" and in the first 30 or seconds of it showing a river, large artefacts are clearly visible on the lower part of the sreen (at least on my display). :c The picture quality is similar to a JPEG image that has been really compressed down. Euro 1080 (MPEG2 1080i) appears quite different. The tennis match that was on at the time looks like a good quality 2 megapixel photo from a digital camera that has sprung to life :d Then again, WM9 squezes the picture down to about 7Mbps where as the HDTV satellite channel had a bitrate of about 17Mbps at the time of watching.
