You need to read up on Enigma and Enigma2 based receivers. Dreambox is the most popular, but I wouldn't call it the "best". From personal experience Vu+ ones blow any Dreambox out of the water. Tuners in DB are generally cr@p, are prone to overheating and cost generally double their cheaper, better, competitors.
There's also CT Xtrends, Technomates running the same OS... but you really need to read up on stuff before making flawed conclusions.
And if you just want to watch TV, just get an official Sky Italy box and watch it using that. I would never watch Sky in my Uno, simply because it's nowhere near as user friendly as a Sky box. Uno is solely for tinkering about (can't remember last I actually properly watched anything on that).
