I would do a little more digging on this one... ;-) I stand by my statement. Remember that it is not what the maximum capabilities are, it is what is being *used*.

The two are not the same in this case... The DDTrueHD track is indeed limited by the master (and also technically by the codec as well due to its bit level), but the uncompressed PCM used in Blu-ray is not up to the level of the orginal master... Close, as I orginally stated, but not quite there.

That said, BRD can use DDTrueHD and DTS MA lossless as well, so my belief is they will move away from the uncompressed PCM, and switch to these codecs like HD DVD in the near future. Their use of the uncompressed PCM is primarily due to the Samsung player on the market not having onboard decoders for either. Once players arrive that do, the uncompressed PCM becomes unnecessary for the most part.
