Thanks for answering this!
I seem to recall reading that having the decoder in the player was closer to the source and could potentially do a better job since it had access to the disc. I could see this if it pre-buffered and read ahead a bit, but I'm not sure. Also, they don't have control of the quality of the decoder in the receiver, not that Dolby directly controls quality in players, just minimum requirements for standardization.
Page 9 of the TrueHD whitepaper go into more detail on this:http://www.dolby.com/assets/pdf/tech...whitepaper.pdf
They say that the receiver could focus on the postprocessing of the audio, not decoding the codec also. Most practical way, but perhaps not the best.
They furthermore give reasons here:http://www.dolby.com/consumer/techno...HD_avrs_1.html
Sort of like the reason why progressive scan DVD players often perform better than TV scalers and deinterlacers.
But, if you know you have a better external processor than built-in, you should be able to send it out via HDMI 1.3 (with required features) to your receiver/processor with same HDMI 1.3 features. Just like people wanting to send 480i over HDMI to their nice video scalers for DVD rather than 480p.
I'm not in this boat and do enjoy the decoders in my HD DVD player sending PCM over HDMI to my receiver and am happy I don't have to buy another receiver. If and when BD disks become good (i.e. BD-50 with VC-1 and video quality consistantly matching or possibly exceeding? HD DVD), I'll probably get a BD player too - but I think it will be probably mid-2007 before this happens IMO. I could live with LPCM tracks and don't need TrueHD or DTS-MA, but think that it is a waste of space on the disk not to have lossless codecs - space that they definately can't afford without BD-50. It's just a matter of time before all of this equipment is HDMI 1.3, but that could take a while. The most interesting feature of HDMI 1.3 for me would be the end of lip-sync issues on the video, since there is a feature in 1.3 to syncronize audio and video.
