I've been reading up on the various formats used on Blu-Ray discs. I plan on picking up a player soon, but it'll be hooked up to a rather old Sony receiver for a time. Not a big deal to me so long as I can still get the lossy codecs via spdif. I understand that DD+, DTS-HD, and DTS-HDMA contain lossy "cores," and TrueHD discs contain a lossy DD track for backwards compatibility. Seems that all the bases are covered...until I read about uncompressed PCM tracks. I was looking at discs today and noticed that Pirates of the Caribbean uses "Uncompressed 5.1 audio." Do discs like this also contain a lossy track, or will I be stuck with the two-channel decode that the player provides?
