Yes after manually setting the output frequency's as per spec sheet now have a,b,c & d configured & working.
Not read the guide fully yet, but assume with a splitter & cable to tuner b, e,f,g & h can also be configured, but set as connected to tuner b.
Can I also assume with the gt-sat lnb with 24 scr's all virtual tuners could be configured without splitter use ?

many thanks for getting me up & running.
