Okay, my Motorola(Comcast) DVR has A/V out connections on it, but when I try to connect something to them, nothing happens, theres an "input" on the remote, i press it and nothing happens. Why are they even there? And why are there USB ports on it? I connect my laptop to it, but then again, nothing happens. lol ( So, do i need software on my computer for it to work on it? and why are there A/V ports on it?)
