How do I get the VCR to pay attention to the Audio In signal,
so that it will be recorded if I record onto a tape in the VCR?

1. Be sure you understand how to SELECT the external
audio/video input. Consult the manual for the VCR.

2. Note that SOME VCRs will NOT record audio-only.
They require having some video input to synchronize to.

Of course, if you are going to end up converting to MP3
(or some computer-based scheme) to listen on the road
or whatever, you are likely far better off just recording
directly on your computer.
