After Microsoft Senior Program Manager Steve Riley announced that HD DVD and Blu-ray will only play in 64-bit version of forthcoming Windows Vista, because Microsoft intentionally crippled HD DVD and Blu-ray support in Vista 32-bit, Microsoft PR manager Adam Anderson said to CNet that the original statement made by Riley is partially incorrect.
“Any next-generation high definition content will not play in x32 at all. This is a decision that the Media Player folks made because there are just too many ways right now for unsigned kernel mode code [to compromise content protection]. The media companies asked us to do this and said they don’t want any of their high definition content to play in x32 at all, because of all of the unsigned malware that runs in kernel mode can get around content protection, so we had to do this,” Riley said during the TechEd 2006 in Sydney.
But, Anderson says “it is up to the ISVs providing playback solutions to determine whether the intended playback environment, including environments with a 32-bit CPU, meets the performance requirements to allow high-definition playback while supporting the guidelines set forth by the content owners”.
“No version of Windows Vista will make a determination as to whether any given piece of content should play back or not”, Microsoft PR manager tells CNet.
