Haven't gotten the DATs but we have a mail room here (we live in a dorm at a boarding school) so it can be slowish at times.
Good point about that dealing with already-existing recordings. I did some further research on California (I'm not a lawyer either, but I'm both bored at work and persistent...heh) and a bit further down the page are 653s and 653u:
653s. (a) Any person who transports or causes to be transported for
monetary or other consideration within this state, any article
containing sounds of a live performance with the knowledge that the
sounds thereon have been recorded or mastered without the consent of
the owner of the sounds of the live performance is guilty of a public
offense punishable as provided in subdivision (g) or (h).
653u. (a) Any person who records or masters or causes to be
recorded or mastered on any article with the intent to sell for
commercial advantage or private financial gain, the sounds of a live
performance with the knowledge that the sounds thereon have been
recorded or mastered without the consent of the owner of the sounds
of the live performance is guilty of a public offense punishable as
provided in subdivisions (d) and (e).
SO - it all hinges on what "transport" means (mail? car? just handing it to someone?), and whether trading constitutes "other consideration" in 653s. Because if you transport recordings made without the artist's permission for "other consideration", it's against the law. But if it's recorded with the artist's permission, you're in the clear.
