I thank you all for your replies; I'm just searching and I will keep you updated about that.
"Though not always the DVDs that are available on the street in Rome. ;-)"
I suppose you are pointing at "non juridically impeccable" duplicated DVDs and CDs, sold everywhere in Italy; Rome is totally honest confronted Naples !!
May be you won't believe this but my father had a job in a software house. He could buy there, from itinerants sellers, beta version from his own company even before them were made available to him for testing! Italy is a strange country, indeed.
Warmest regards.
ciao !!!
