Could anyone tell me why HD-DVD or Blu-Ray is any better than WMV-HD or Quicktime-HD that plays at 1080p on my P4 3Ghz with 256MB Radeon 9600 and Avio drivers no problemo. I can get Terminator 2 in WMV-HD for $7.99 or rip it to a DVD-DL (the entire movie is less than 7GB) and get true 1080p HD on my TV or monitor via my PC using Windows Media Player with K-lite codecs. Why do I need HD-DVD or Blu-Ray and all the ultra-expensive hardware when the delivery system already exists for my current PC? Can't we simply re-encode HD-DVD/Blu-Ray files to WMV-HD? It seems to me it's not about 1080p definition but just mega-huge files and mega-huge expense.
