yep, they are out there, even in form of HD-DVD rip now. I just found Riddick and dl-ed an .nfo file. (for edu purposes only)
Here it is:
Video: 1920x1080 29.97fps 1080p VC-1
Audio: English (DD+ & DTS), Spanish, French, English directors commentary. (Only English DD+ track playable with PowerDVD.)
All files are in some EVO format, including two by 10 gig or so.
What is EVO anyway?
