2.800 firmware

Has anyone else seen their IPC-HFW1831E bitrate acting strange with 2.800 firmware? Since updating my cameras to 2.800 firmware, I'm seeing bitrates twice, sometimes more, than what the camera is set at. (Set to 8Mb/s, but I see bitrates up to 16-20 Mb/s) I did not see this with 2.622...
