I have what I think is a pertinent question here;  are the signal levels
within TVs/VCRs consistent with "line-level" standards?  I suppose as long
as you find the right place in the TV/VCR, you could convert a signal to
the correct level, but is that necessary, or is there consistently somewhere
to just tap right in?
