Do you see that with other movies as well?
According to the log file, CloneBD tells nVidia to use 56mbits as bit rate, limits to a maximum of 89mbits and sends in the complete 1:35h of video.
So that should amount to roughly 40GB video data plus a few GB audio.
CloneBD seems to be doing everything right - actually achieving the requested bit rate is in the hands of the nVidia drivers.
In your first post (cbd 1.2.4.0), there was an actual bug, CloneBD telling nVidia to limit the maximum bit rate to a nonsensically small value, but that is no longer the case.
