my serious advice to you not to search for it, why?
i tried below TV Tuners with Windows 7 32/64
- Pinnacle PVTC Rave
- Pinnacle PCTV Stereo
- Asus My cinema
- MSI TV Pro Master
no card worked !!!!!!
All card's was installed successfully, properly shown in Device manager but no TV Display
the only card showed display but without Sound was Leadtek Winfast Expert
so, be careful because sometimes the manufacture of card say it works with Win7 but practically it does not work
