excuse me  did i forgot to say that i am totally a newbie?
what is the datasheet of PLL and where is the 5 byte i shall send to the tuner? 

the things i did was only to change some values in static struct tunertype tuners in tuner.c
i gained some frequencies but still some are missing

same thing what is the newstruct branch?
can i just use the driver i got ? 
its the dvb-20020611
can i just tell you which frequencies are working and which are not?
thank you
