I received my new TiVo (80 hour series 2 dual tuner) that I ordered last week. I have it hooked up with RF in, composite to the TV. I've verified that my TV is working properly, hooked all the cables up correctly, etc. I've tried restarting the unit, and still nothing. Can anyone provide any suggestions? I'd hate for it to be a bad hard drive, but that's what I'm leaning towards.
Edit: I fixed it. I had the composite cables plugged into the "in" ports on the unit, not the "out" ports.
Moral: don't try and hook up audio-visual equipment after getting home from a 12-hour day. I will leave this thread as a reminder of what not to do.
