Are they ‘DTS HD' or ‘DTS HD Master Audio' though, as only the latter is now the term used to represent DTS' form of lossless packing. DTS HD is just a new term for 1509kbps full bitrate DTS, though content providers are still free to simply refer to full bitrate DTS as plain old DTS on their packaging.
For example, on HD DVD, some Universal titles and most/all Paramount titles have a full bitrate DTS track. Sky Captain has an advertised DTS HD track, but it's actually just full bitrate lossy DTS like on other Universal/Paramount discs, but this isn't a marketing blunder, as it is in fact correct advertising, just inconsistent.
DTS essentially wanted to market themselves better to oppose Dolby Digital Plus, so they rebranded the lossy encoding as 'DTS HD' to make it sound like something new and important, and subsequently DTS' lossless presentation format became known as DTS HD Master Audio.
Surely we are about to see the first BD50? Black Hawk Down seems to be still scheduled for August 15. BluRay has alot riding on that release and I'm sure they would have issued a press release if it was going to be delayed...
Remains to be seen. We might just find that Black Hawk Down was quietly downgraded to single layer. When they actually announced it the spec still showed it to be rather stripped back in terms of delivering all the special features the deluxe edition DVD offered, so it's either 25gb or it's the first 50gb that might in itself be a joke because the boast of all that space still wouldn't allow them to bring over everything from the DVD thanks to their instance on siding with MPEG2 and uncompressed PCM (when ironically if the film
and extras were all VC1 encoded they could get the movie and its two discs worth of DVD special features onto a dual layer 30gb HD DVD with potential room to spare for a TrueHD track).
