I bought a bluetooth dongle and had to return because it did not like W8(or viceversa). Now I wonder if USB TV Tuner is likewise OS specific. Does anyone know any particular model/brand that is sure to work with W8?

I also really do not know what exactly does TV Tuner do. Do I get to watch live TV like I used to with TV Tuner express card with Media Center Edition(of XP and Vista days)? And schedule live show taping for two weeks?
