Uncompressed or Dolby Digital?

Sort of. What you referred to is HD disc spec. The TrueHD codec itself has this:

What is the sampling frequency and word
length for multichannel Dolby TrueHD?
Dolby TrueHD for next-generation high definition
media delivers sampling frequencies
from 48 to 192 kHz and word lengths from
16 to 24 bits.

I'm pretty sure they're lumping in HD DVD when they refer to HD media spec. Since THD is optional on Blu-ray I don't see what's to prevent a program provider from encoding it at 192kHz if they wanted to. Besides, do you really think that you or I could tell the difference between a 24 bit PCM track at 96kHz or at 192kHz?

I work with audio every day, I can hear the difference between 192/24 and 96/24, but it's not a debate I want to get in to. But, as far as TrueHD supporting 192/24 at 5.1, I have found nothing anywhere to suggest that this is supported in the Blu-ray specification, and that is what we are talking about. AFAIK, TrueHD is only supported up to 96/24 in the Blu-ray spec. For the purposes of this conversation, who cares what it can do outside of the Blu-ray technology? It doesn't matter if it's optional or not, so I don't know why you would even mention that. Optional doesn't mean, anyone can come in and implement it to whatever spec. they want.

TrueHD also supports the multiple 7.1 configurations DTS has been touting lately.

Did someone even mention this?

Plus, it can't be decompressed and no one knows when.

Oh, really? Onkyo seems to know when, because they are shipping receivers right now that decode DTS-HD MA. So, what are you talking about?

A year past launch and we're still waiting.

Really? TX-SR605
