Hello I have a kworld tv/radio fm card works ok av video (composite) works bad tv reception just get video and not sound uses a cable tv card to sound card (sound blaster that works great ) even in windoze i need to switch tv radio to get sound does somebody has one kworld card using tv and radio successfully or is better idea get a pinnacle tv card? By the way the radio does not work nothing. is bt878 i used a file called bttvconfig with almost the same results than with automatic config from YaSt pd somebody has a pinnacle working fine or is also the sama problems an the same bt878 chip? I know they share the conexant chip but i do not know if the radio aspirations in my card are wrecking all the sound reception. Thanks at all
