Vista requires premium content like HD movies to be degraded in quality when it is sent to high-quality outputs, like DVI. Users will see status codes that say 'graphics OPM resolution too high'. There are ways to bypass the Windows Vista protection by encoding the movies using alternative codecs like X264, or DiVX, which are in fact more effective sometimes then Windows own WMV codec. These codecs are quite common on HD video Bittorrent sites, or Newsgroups."
