Thanks Paul,
I get it now, that answers my question about channel 3 etc.. The
firewire option would need the satellite receiver to have this port and
be enabled, so I hope this is so. This particular person has another
satellite receiver for a second TV upstairs and it uses a wireless
connection for that, so if no firewire, I may have to do the IR Blaster
option. Thanks again, Peter
