my win 7 pro 64 bit will not work with three recommened tv tuners, though not specific to 64 bit . I know one works great withmy old 32 bit xp system. all three different recommended tuners crashed my system three times amd informed me the flash player that comes in the software is not compatable with my system. also flash player stand along in my system will not work right all the time. worked so well in my old system? any thoughts on this dilemma. really do not want to return my new diamond tv wonder hd 750 card. otherwise this system blazes very appy with it, thanks.
