How do you record a TV show from the TV to the VCR with no camera connections?

Simple. Have the cable connection go into the vcr first to the in connection and from there use the out connection to connect to the tv in connection. Now you have all the same channels on the vcr as you do on the tv. If you have a cable box keep the vcr and tv set to the proper channel 3 or 4. If you are working with an antenna it is the same. If you want to watch and record different programs at the same time you will need to split the antenna or cable connection so that each unit gets its own clean signal and tune each devise to the desired channel.
