I have a Presidian 16-163 dvd recorder. Does anyone know what type of blank dvd's to use with this? It has no manual, bought off ebay. Also, if I buy a hdmi to rca converter adapter cord https://www.radioshack.com/products/radioshack-hdmi-to-component-converter?varia nt=20332530501 will this allow me to record over the air digital tv?
