Look at the connections your devices have, match them up to connect to the TV. If you don't have a certain connection available, look for converters to change it to what you do have. To copy VHS to DVD you need to have them connected to each-other directly and use the pass-through signal to send the output to the TV also to monitor things. Just hit record on the DVD recorder when the VHS tape is playing. Note if the tape is copy protected it may end up with a scrambled image.
