yes I agree with what Jimbo 2015 is saying. I have tuned failed issues with two cable tuners , you can be watching bbc1 then flick to say channel 4 then back to bbc1 then tuned failed again.
I have tried different firmware inc vix hades , Adonis ,and openpli all resulting in the same tune failed issue.
They seems to be not much support for this box, I have sent the box back to supplier who have in-tern sent it to manufacturers thinking and hoping it is a hardware problem. It has been 3 week now and still waiting for box to be returned. any thoughts appreciated.
