I have currently dish network and basic cable connected to the unit. I would like to add another satellite receiver from GlobeCast (international channels). Can it be done? I know that there is one extra input but how do I set it up? In setup, only dish and directv are listed. I don't need IR blaster because I will only watch one channel? I will have to use manual recordings since no guide will be provided. But how do I set manual recoding to use the other input?
