You will need a convertor box.
The one I got is http://www.amazon.com/gp/product/B00I482L2K/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1#
Make sure you get one with the THREE Composite ports.
Do NOT get the component ports.
This will allow you to plug in through your VCR, DVD player, or just right into the TV. It works great and I have not had a problem with mine using it with my Googlechromecast. I've been using it for about 2 months now with no problems.
