LD vs. DVDs
James Wight
more or less compressed in size than DVDs? and what about the quality?
does it have much more or much less noise in the video?

It depends on the type of audio.
Starting from oldest to newest:
straight analog: uncompressed and noisy as hell; never seen it in use
CX: compressed, less noisy
Digital Audio: Cd quality, uncompressed. Is a seperate set of tracks from
analog audio
AC3 dolby digital: up to 5.1 channels; compressed; similar to DVD DD
uses right analog track
DTS: up to 5.1 channels; compressed, but less so than DD; similar to DVD DTS
uses left/right digital audio tracks

This is a topic that really does not need to be hashed out in this
newsgroup for the 18 millionth time.
In short, here's the FAQ:

No, AFM Hi-fi in analog and RF Dolby D is not described here, it is a codec.
DTS is slightly compressed and carried in the digital track section of LD... It
can be recorded to digital tape (DAT) or MiniDisc and played back thru a
decoder... DVD can't do that with digital audio.
The regular stereo PCM is Redbook (same as CD)

Bill, you pathetic, lying, thieving moron.
DTS is highly compressed on LD and DVD, somewhat more on DVD if the
768kbps option is used.
Yes, any DVD digital audio can be recorded, any of it.

Like a blind squirrel, even Bill can find a nut once in a great while.

salvation remains in the MLP format! :)
I had in mind that AC3 was about 1:8 to 1:12.

DTS certainly cannot be recorded to minidisc. Whether it can be
recorded to DAT depends on the setting of the copybit and this is
valid for both LD and DVD.

Since DTS and DD are both lossy compression schemes and MLP isn't, you
might be right, but only when bandwidth isn't an issue.

Since the encoding schemes are very different, direct comparisons of
bitrates can't be used as an objective measure of accuracy.

I hadn't tried it to Mini yet...will do.
Also, It was some time I recorded DTS to DAT, but it works and I don't recall
any luck with DVD. I have my players operational again so I'll try all this.
Thanks the input.

That will not work because the Minidisc is compressed.

I only depends on the setting of the copybit.

ATRAC system?
As for DAT, I bought media drive tapes from Hewlett Packard and they appear to
work fine for digital recording. The DAT deck I have only allows long play and
standard play, at the 32kHz and 48kHz.
I don't have a factory remote or manual, so if there's other adjustments, I'm
unaware.
Also, I used optical connections for digital recording, and saved my DTS audio
CDs to the DAT medium.
Most of my MiniDisc archives are of cassette tapes that are worn. The MD allows
some nice convenience over DAT, but DAT sounds great.
