    is it likey there will be noticeable quality in movies on different formats but encoded in the same resolution?

    such as say Tomb Raider WM9 and HD-DVD(when it arrives) or are they likely to look the same?

    I have seen some of these US sat movies like master and commander and Star Trek first contact, and they look like they could use a smigen more bitrate if u see what I mean

    The current WMVHD titles are limited to DVD's maximum bitrate of 10 Mbps, even those at 1080p resolution. Titles on HD DVD and Blu-ray in 1080p24 will (hopefully) be released with bitrates around the 14-16 Mbps bitrate for MPEG-4 AVC and VC-1 codecs which has been tested to give the optimum PQ. So, in theory, there should be an increase in quality over the currently released titles in WMVHD. Hope this helps.

    I thought we would see higher bitrates for HD DVD and Blu-Ray Dutch? Interesting.

    The current HD broadcast material - like M&C and Star T 1st Contact -can look a little "off focus" and grainy - not sure on the process employed by the TV channels, but I would expect an official HD release on HD or Blu-Ray to look even better.

    Roger,

    Tests carried out by the Blu-ray Disc Founders found that around 16 Mbps was the "sweetspot" for best picture quality - increasing this to 20 Mbps got a lower "score" from the test material observers.

    That's quite interesting - would love to see the difference myself.
