Short answer:
DD5.1 is compressed.... DTS-Master Audio and Dolby TrueHD are not.

Ok, technically DTS-MA and Dolby TrueHD ARE compressed, but they are more like a .zip file. extract the data from that file and you get the full lossless (uncompressed) audio in perfect form. DD5.1 is compressed much like an .mp3 is compressed. It literally throws away a lot of data to save space. Now, the problem is that just like some .mp3 files, the level of compression can vary from one source to another.

In the movie sound industry, HD audio is reserved for uncompressed or lossless audio like DTS-MA and Dolby TrueHD, and DD5.1 is just considered a sub-par audio track that is missing a lot of information. It is still surround sound, but it is like saying that the DVD that the DD5.1 audio is on is HD when comparing the DVD to a blu-ray which is in HD.

Now, do I really care what you enjoy? Heck no. Play what you want and enjoy it. You are missing out on what you *could* hear, but you seem fine with what you *currently* hear and who am I to spend your money on something that you don't think that you need.
