I wasn't having any problems, but just updated to 4.4.8.5 x64. Avoid. One camera, Trivision NC 336, video is heavily distorted jumping around and triggering recording. Another camera had motion detection zone reset to cover full view. Tried rebooting, changing camera type and back, reinstall etc no luck. 4.4.8.5 is bad.
Similar thing happened a year or so ago with others reporting same problem on here. Is there really no method or link to previous versions to allow us to revert and save the headache?
