Sorry, I probably have been a bit obscure.
What I meant was are the "alternative mixes" on the SACD just the standard mixes of those tracks as opposed to new 5.1 mixes from the masters or some other previously unreleased mix?
The question behind the question is if it is possible for the three bonus tracks on the SACD to have DVDA watermarking embedded into them because they had originally been prepared for the DVDA release?
If - in theory - someone were to rip all the tracks from the SACD and create a DVDA from them, is it possible that when played in watermark-detecting DVDA player that the main album tracks would be fine, but the three bonus tracks would trigger the watermark detection and not play?
