Adding a passthrough device to an Activity
A passthrough device is a device that you add to your system that a signal passes 
through unaltered. 
For example, if you use your DVD recorder (or VCR) to record shows from your cable or 
satellite receiver, you may need to add your DVD recorder as a passthrough device to 
the Watch TV Activity.
In these examples, the DVD recorder and the A/V switch are used as passthrough 
devices.
