Thanks guys. (I don't know how I haven't seen that option

)
It should be more than enough.
I'm on holidays the whole Holy Week, so I'll test it next one...
EDITED----
Obiously, fully confirmed.
I've just changed the default
Code:
{author_sort}/{title} - {authors}
into
Code:
{author_sort}/{title} - {authors} - {publisher}
For the time being it's perfect. If I find an extremely strange case where this info is duplicated, I'll made further tweaks but obviously no change is needed in the driver...
