Usually you use an RCA based cable to hookup the Video output from the source machine to the video input of the recording one. Then an RCA cable for each audio channel...one from audio output Right channel to input...same for left channel. That's three RCA cables total.

Also if there in an "Edit" feature on one of the machines then use that as the source VCR. This button/feature strengthens the signal for this purpose.
