Help re the 'Alternate Services' tuner function please:
I have a Duo with an additional USB terrestrial tuner.
I understand that it can be configured so that the USB tuner will become effectively a third 'auto-select' tuner - Just as the auto-select from tuner A & B.
Please can someone explain how to use the 'Alternative Services' function? (or point me toward a how-to guide).
Thanks in advance.
