Does that give me an unprotected copy of the DVD suitable for burning later?

Yes, if it was switched on in AnyDVD the moment you copied to the harddisk. Best thing to do is start a player software before you copy - so you see exactly what you'll get- Maybe you should enable "remove annyoing adverts & trailers".
> Or did I misunderstood how AnyDVD works - my understanding was that the files were filtered/changed on the driver level, so that Windows only sees unprotected files?! <
No, your understanding is quite correct.

No, not that I know of.
