How does Beyond TV know which tuner to use?
By default, Beyond TV will use the first configured tuner device that is capable of tuning the channel on which the show appears. For example, imagine that you have a PVR-150 (on Basic Cable) and a PVR-250 (on Digital Cable) and you configure the PVR-250 first and PVR-150 second in the Setup Wizard. If you schedule one recording, it will be performed on the PVR-250, as the first configured tuner source, even if the Basic (analog) cable lineup has the same channel available to it. A good rule of thumb is to configure last the tuner you want used least; in the above example, this means configuring the Basic Cable tuner first, and the Digital Cable tuner second.
