I have to do more testing, but it seems like in some situations, it will overexpose 2/3rds over what live view exposes. I have taken all suggestions.
I for one love auto iso. I'll do more testing though to make sure it isn't just me (most of the time it is)
Initially as you explained it the problem was specific to Auto ISO. But based on the above I believe you're just getting a different metering/reading in LV vs non-LV, and it just happens that the different reading is reflected in the ISO because you're using Auto ISO. It's not uncommon for LV to expose differently than non-LV, since in LV metering is performed off the image sensor instead of the metering sensor. Nikon's LV metering algorithm is designed to meter as close as possible to the traditional, non-LV metering sensors but there are situations where that wont be the case. I believe that's what you're seeing. You can verify this by reproducing a scene that shows what you believed to be an Auto ISO difference and then just turn off Auto ISO and observe that it's really a metering difference.
