http://bluray.highdefdigest.com/news...or_Blu-ray/209 This comports with what industry sources were telling me a few months ago. I look forward to seeing what VC1 on BD can do... basically, aside from any "player" issues, the PQ from BD and HD DVD should be identical for most standard program titles using VC1 on HD DVD 30/BD25. For those of you not up to speed on the history here... When Sony launched BD a few months back they hadn't gotten the authoring tools ready to enable studios to encode Blu-ray discs using VC1. That's why all the early BD discs have used (the inferior) MPEG2 video codec which is one reason why they typically don't look as good as HD DVD discs which pretty much are all using VC1 from the start (at least the discs by major studios. Rattle and Hum was AVC which is MPEG4). The authoring tools for VC1 are now ready for BD and Warner Brothers will be releasing *** all *** of their BDs using VC1 from this point forward. Just a FYI... the authoring has been availble now for a while but the hold up with VC1 on BD the last month or so has actually been by the player manufacturers who wanted more time to test the software to ensure proper preformance with their soon-to-be-released hardware (so I've been told by industry insiders). It will be interesting to see how this may affect the viability of Blu-ray while the BD camp works out the issues of 50 gig compatibility. Let's keep this thread from turning into another generic format debate and try to keep posts germane to the topic of VC1 on Blu-ray. -dave p.s. don't let the DD+ on HD DVD versus the standard DD on Blu-ray fool you. Roger Dressler has indicated that with 5.1 tracks the 640 kbps DD on Blu-ray is basically providing the same qualtiy as 5.1 DD+ on HD DVD. The use of DD+ for 5.1 on HD DVD has to do with the way the data is packed on the disc in order to increase the bit-rate beyond the 448 kbps max-limit for DD on DVD-formatted discs. I know that's not the topic of this thread but that issue has confused many of us in the past who wondered why HD DVD was using DD+ compared to BD providing standard DD for the same titles on both formats, and according to Roger from Dolby the end result is more-or-less the same as the DD+ on HD DVD in 5.1 mode is basically providing DD quality at @ the 640 kbps rate (which cannot be encoded natively on HD DVD due to the 448 kbps limit on DD).
