Why won't this receiver have problems if what you say here is true? I am sending your comment here to Jeff at Sherwood-Newcastle for his consideration. Perhaps one can select on the 972 whether or not to have it decode the PCM audio signals. I hope so if you are right, because I intend to buy a 972.
If you are receiving high bandwidth, multi-channel PCM over the HDMI connection then the audio has *ALREADY* been decoded from the packed audio track (i.e., from the Dolby TrueHD or DTS-HD MA track). Either it was decoded in the player or the disc contained a raw PCM track that doesn't need decoding. The result of decoding is a set of digital audio PCM streams -- one per speaker. You can send this over HDMI V1.1 or higher to an appropriate receiver.
Decoding in the receiver is only necessary when you try to send the STILL ENCODED "bitstream" -- the TrueHD or DTS-HD MA data as it comes off the disc. This can be done with HDMI V1.3 or higher at both ends if the receiver also has decoders built in.
But "advanced content" discs won't work right if you do that. Such discs have to be decoded in THE PLAYER so that the player can do the audio mixing that's implied by such authoring. The receiver can't do that mixing because it can't see the various different streams of audio that need to be mixed.
Almost all HD-DVD discs are "advanced" today and that is likely to continue into the future. Blu-Ray discs are "basic" today, but the expectation is that Blu-Ray discs will start being authored for "player profile 1.1" -- which has the same sort of restrictions -- as early as this summer.
For playing such discs properly, you will need to buy a player which has decoders for the new, high bandwidth formats of interest to you -- or will be upgraded to add them.
The decoders in the receiver will still be useful for an HDMI V1.3 Blu-Ray player playing current titles. They may also be useful for other sources.
