So, it sounds like there is more current on one of the neutral, ground
since I last measured (I wonder if hooking up the tv upstairs to the cable
line could have some effect on this).
You have to remember that there is not supposed to be any current
flow in the safety ground, so it will have the same voltage as the
ground buss bar in your breaker box. So, when you connect the meter
between neutral and ground, you are measuring the voltage drop on the
neutral conductor, only. The higher the load on that circuit, whether
at that outlet, or another will show on your meter. Your meter should
have a 10 Megohm input impedance, so the ohm or so resistance of the
ground wire won't affect the reading.
