Does unplugging the rca connector from a dvd player toy with the set-up?

I recently got a friend to set up my new dvd player for me. I realize now that he used the rca connector from my vcr to hook up the dvd player to the tv. I cannot find another rca connector. If I unplug the rca connector from my dvd player and plug it into my vcr, will that toy with the set-up of my new dvd player?|||It won't change any settings on the DVD player.|||It will not change anything. I recommend you purchase a component cable and an optical cable for your dvd player. This would improve the picture quality instead of using rca cables. Hope this will help you out.
