The funny thing is this past weekend I created an HD-DVD in DVD Studio Pro 4, and it encoded not in H.264, but rather in MPEG-2.ehurtley said:It creates what Apple calls a High Definition DVD; but it is *NOT* the same as the new standard called "HD-DVD". It encodes HD in H.264 and burns it onto a standard 4.7 or 8.5 GB DVD (or DVD DL.)
They will play back on any recent Mac running 10.4.1 or higher (10.4.1 is when Apple DVD Player got the ability to play them back.) (Obviously, it helps if the Mac is fast enough...) But, they are *NOT* compatible with HD-DVD or BluRay commercial players, and not compatible with PCs.
Curiously, the high definition DVDs from DVD Studio Pro do indeed conform to the preliminary spec for HD-DVD. Such DVDs are confirmed as working on a prototype Toshiba HD-DVD player. Now that the HD-DVD spec is apparently finalized, Apple will either issue an update to DVD Studio Pro 4 or make us pay extra for final spec compliance in DVDSP 5.
I just looked at bestbuy.com and apparently the Toshiba HD-DVD player is in stock at stores. I'll take my recently created (red laser, DVDSP 4 authored) HD-DVD to Best Buy either tomorrow or Wednesday to test.
For PCs, one needs to author a WMV-HD disc.
