XBOX Live Marketplace vs. HD-DVD
PVRWire has the scoop on a comparison between a downloaded HD movie from the Xbox Live Marketplace and a HD-DVD movie. Looking at the screenshot, it appears that the downloaded movies do fairly well when compared to the stand alone movie.
With the current limited selection of movies available in both HD-DVD and the
WMV HD format used by Xbox Video Marketplace, I used V for Vendetta as my movie
of comparison. Watching each movie independently, I could find no artifacts in
either video file, no macro blocks during motion sequences, and a great range of
colors in both cases. The Xbox Video Marketplace file looked just slightly
brighter than the HD-DVD, but overall I couldn't tell any real difference.
