Someone help me please!! I bought a Tivo PTV300 from someone who assured me it was working. I have tried hooking it up but get a message that says "your recorder is starting up, please wait a moment." I wait for hours and nothing happens. Am I doing something wrong or was I ripped off? I am going straight from the tv to the tivo, so there are no boxes or other things to contend with. Anyone out there help me?
