> Are you going to put up a new .iso for download using Rec. 709,
No plans at this time. I don't have a pro level authoring tool for HD-DVD and I'm pretty sure mine won't compile a HD-DVD. Plus, to get around clipping issues with consumer encoders and authoring tools, I'm having to use custom programmed bits and pieces along the way. It's those details that make this disc as accurate as it is. We can thank dr1394 for that, would not have done it without his help. Authoring the DVD was my forte, dr1394 is the mpeg expert.

No, it would represent a complete re-do, really a different disc, I'd start it as a different project. Not like the current one is very expensive

No, it's "digital component" if you will. YPbPr is analog component. See:http://www.answers.com/topic/ycbcr

Depends on who's doing the RGB conversion and where.

I'm no HTPC person, but generally, in the case of a PC, you'd have to tell it which RGB transform it was supposed to be using if you were calibrating for a 709 output I suppose. Like a standalone player, you may not get the option to tell it what RGB transform to use when decoding a SD DVD. I presume it would be a software decoder so it would depend on the software. The YCbCr values on a SD and a HD-DVD disc are the same. That's what's on the DVD. I dont' know what's on BD material right now, haven't been keeping up. It's what the device does with that info when converting to RGB that is unknown. If it sees it's a SD DVD and automatically applies a SD R601 RGB transform to it, then it would be off for the HD colorspace.
