I have PlayTV usb 415 "PixelView" usb tv card and I have all drivers installed for this TV card on my PC. But when I tray to watch TV, there is no picture - everything is black. I am using Windows Media Center. I can see channel number and everything else (icons) but there is no picture and sound. Everything else does working in Media Center. Also I tried other softwares like VentiTV and Presto PVR but the problem is still the same. Please, if someone know how to fix this, answer!!
