1) Shipping DVDs shouldn't take any longer than shipping books.
I have so far only ordered books at amazon.de. These were delivered in two workdays. You can track amazon's parcels via a link on their website.
2) What do you mean by "controlling" deliveries?
Of course, their system retains any available information on you: What items you viewed on the site, what you ordered, etc.
That's how they generate "recommendations" tailored spefically for you whenever you visit the site.
I don't think, your purchase of softcore DVDs is anything the CIA or Wolfgang Schäuble might be interested in.
On the other hand, I wouldn't recommend ordering a copy of
How to Build a Dirty Bomb? or back issues of
Konkret.
