Rebooting problem Openbox

If you do find yourself selecting a channel that reboots the receiver constantly, simply turn Off the receiver and disconnect the Lnb cable, once the Lnb cable has been disconnected, start the receiver and then click Menu -> TV Channel List and delete the channels, then turn Off the receiver and reconnect the Lnb cable, start the receiver and all will be okay.
For those of you with a motorsied setup, simply use the positioner to move the dish to a position where you get no signal, then you can edit the channels without the need for disconnecting the Lnb cable.
