AFAIK, DTS Entertainment sells surround music on these 3 formats:
1)
DTS-CD/DTS Music Disc - these play on any CD player (but ONLY through its digital output) or dvd player connected to a receiver with a DTS decoder. I own the Moody's
Seventh Sojourn album on DTS-CD.
These were repackaged around 2002 using a dvd-audio "super" jewel box and retitled DTS Music Discs, I think because of what Christopher said (i.e. the actual data on the disc does not conform to CD specs, even though the
physical disc does). Now I'm seeing them again in regular CD jewel boxes but still with the new name.
>>> I thought any dvd player that had an onboard DTS decoder would play these through its own analog outputs (my Pioneer DV-656 does), but I've read where certain Samsung universals don't - weird.
BTW: some of their last DTS-CDs used the DTS-ES format, a
6.1 format, like Midnight Oil's
Capricornia
2)
dvd-video disc + CD package - a plain ol' regular dvd with DTS, DTS-ES or DTS96/24 (still lossy but has extended high frequencies) plus a stereo PCM track, usually 48kHz/24bit. I own one, LTJ Bukem's
Planet Earth, downtempo/drum-n-bass music.
3)
dvd-audio discs - their very early ones had Dolby Digital mixes but now they seem to exclusively contain their own proprietary formats. Many of them contain 96/24 "regular" PCM stereo tracks that 99% of all dvd players can play.
Grant: I know sound is very subjective, but if the sound you heard was muffled, it's probably because that Queen recording - the sound itself, not the mix - was never that stellar in the first place. If anything, at least on the dvd-audios I own, the DTS mix usually sounds a bit
brighter than the MLP tracks. But if you bought that disc used, you might want to read
this article at HFR &
this one* by HTF's own Felix Martinez about the mixing debacle surrounding that disc, and how Brian May had to step in and help completely remix it so it sounded right on the
second version that was sold.

from that review: "However, the ambitious recording, re-recording and edits used in creating ANATO over 25 years ago contributed to a compromised fidelity. Distortion, compression, and other recording anomalies were evident even in the original master tapes."
