substance wrote: None of the Hi-Vision LDs had AC-3 or DTS. Muse encoding had its own codec called "Dance" which came in either 2.0ch or 4.0ch( Left, Right, Center, Mono Rear) flavors. Some discs also had 2.0ch PCM soundtrack in addition to the Dance soundtrack.
Dance soundtrack is decoded and outputted from the Muse decoder. 2ch version is 16bit 48kHz and 4.0ch version is 12bit 32kHz, both in about 1.4mbps. Muse decoders have 4 ch analog outputs or 2 digital coax to output 4.0ch audio.
DTS and AC-3 was possible on Hi-vision Ld but never was implemented. Interesting. So arguably standard LD with its 5.1 AC-3 & DTS capabilities means that it can output better sound quality than Hi-Vision MUSE LD with its 2.0 & 4.0 "dance" audio? Of course picture quality is a different story, with Hi-Vision MUSE at best being something in between DVD and BD. Better than the former, but not quite as good as the latter.

You are talking theory here Alien Only a few of the Scenery Discs look better than DVD quality, and can probably get somewhat close to nowadays HD media. None of the movie discs manage this (IMHO).

Yes, I agree. The "Paris" disc I have looks more or less like a DVD. The "Okinawa Underwater" disc however truly has HD-quality in my opinion. The Suzuka Formula 1 disc I have looks very nice, too, considering the video was shot in 1991. It most certainly looks better than a DVD and the whole disc is approximately 90 minutes long which is much longer than most non-movie titles.
