Subject: MD: Super Audio CD not so Super for MDers
Sorry Jay, I just realised you actually had an on-topic element to your
question. With respect to copying Super Audio CDs digitally...
"Built-In Protection
To guard against unauthorized copying, SACD employs
both invisible and visible watermarking on the disk, and
content is encrypted before recording. The SACD
players will have no digital output for the SACD signal."

So we're talking an insurmountable equivalent of SCMS zero-copies, with an
option on tracing anyone who makes an analogue copy via the watermark.
(BTW, does anyone know what use an invisible watermark would be?!)
And you thought V2 were nasty... :-)
As for DVD-A, I don't know exactly how that will end up. I think digital
recordings of PCM streams from DVD players are allowed, so DVD-A shouldn't
be any different. But I reserve the right to be very, very wrong.

End.
Not that I like any of this but we have already likely lost the battle on
superCD though it is my guess the format will never catch on. With Super CD
audio the standard is set and everyone will adhere to it. With V2 they seem
to be the only ones doing it so I think we have a good chance. It's not the
standard so all we have to do is make them adhere to the standard unlike
Super CD audio.
Respectfully,
Mark,
Always keeping the battle going. And yes V2 is nasty both in acts and in
responses to consumers.
