no cable box just TiVo.Where does the TiVo receive its signal from?

I think I nailed it by attaching earth ground to Denon Receivers chassis ground.

Not a good idea. If the Denon has a two wire polarized plug that means the equipment was designed and manufactured with double insulated ac power wiring, therefore an equipment ground (third wire) is not used. An earth ground connected to the chassis could degrade the sonics of the unit. More than likely the signal ground of the unit is connected to the chassis. By earth grounding the chassis EMI/RFI AC noise could enter the electronics of the unit through the ground wire.
