Why should the decoded PCM coming out of PS3 necessarily be equal to what's actually on the DTS-HD/MA bitstream? Unless you're saying the decoded PCM actually provides the same hirez 24-bit, 96Khz audio quality as the encoded DTS-HD/MA bitstream, rather than a downconverted version of that like say 16-bit, 48Khz, which is what I would assume, if not told otherwise. Afterall, if the decoded PCM is indeed exactly equal, then wouldn't it actually require *higher* audio data bandwidth than the bitstream itself?? I seriously doubt that's actually the case considering the argument that the PS3 doesn't have good enough HDMI hardware to handle the bitstream in the first place.

What does Dolby TrueHD use? I imagine the decoded PCM of that would probably come closer to full fidelity.
