It appears you have an amplifier built-into the antenna and another separate amplifier?

If so, your signal is almost certainly too hot for the HDHomerun device.  Television sets generally have additional circuitry that attenuates the signal back down to something usable.  That probably accounts for your TV locking onto signals and the HDHR not.
