I don't know if this will help or not, but I think the DTS-HD thing shows how DTS managed to confuse everyone...
For example, the Toshiba players claim support for DTS-HD using an old style DTS-HD logo. At one point DTS appeared to re-brand the WHOLE of the DTS product line as DTS-HD. This meant that what was originally DTS at 1.5Mbps could be referred to as DTS-HD. This can be seen by the picture shown in this thread of a DTS-HD ES option, which is in fact no more than DTS ES, hence it can be passed as a bitstream to a decoder. They've now settled on new branding, see here
, and as you can see, there is now no such thing as DTS-HD on its own, only with either HR or MA after it. Blame DTS, I think they really messed up bigtime there confusing everyone in the process.
Now in the case of the Toshiba, it does not do DTS-HD HR or MA, so it would seem this Sony.
This Sony unit though (and the BDP-S1) ARE capable of doing DTS-HD HR decoding. This is because they use the Sigma 8634 processor and Sigma themselves write the audio decoding software. The manufacturer, in this case Sony, can then choose to integrate that software into their players firmware, or not. Panasonic have done this (also Sigma based) but to be honest, I doubt there will ever be many DTS-HD HR discs, or for that matter Dolby Digital Plus on Blu-ray.
DTS-HD Master Audio, the one we all want depends on one thing, the revision letter of the Sigma 8634 processor. The BDP-S1 (like the original Panasonic BD10 and Pioneer HD1) had the Revision A chip which cannot
be upgraded to perform MA processing (not enough grunt).
The question is, what do the S300, BD10A and 94HD have inside them? If it is revision A, then I'm sorry but they will never do DTS-HD MA or indeed BD Video Profile 1.1. IF however they have, I believe, Revision C under the hood, then you may be in luck. That revision can do DTS-HD MA decoding, although I don't know if Sigma have the software ready yet, and other in player hardware permitting, may be possible to upgrade the machine to BD Video Profile 1.1.
Why would they not advertise that? Well, everyone knows that there is an October deadline after which any player launched must comply with profile 1.1. However, any player released before then can continue to be sold, and does not have to be upgraded. So, if they feel they may have issues with software in meeting that deadline, if they release a player with the hardware built in before, they cut themselves some slack in getting Profile 1.1 working. Now this is just speculation on my part.
What we really need some brave person to do is just remove the cover of their S300 and take a photo of the Sigma chip and post it. Keith Jack from Sigma has posted a picture, but he's teasing us
by not making it detailed enough to show his companies processor revision no.... which is the all important bit.
