Paranormal Activity Alternate Ending

Last week I noticed a version on the intertubes that was labeled "unrated alternate cut" so I had to see what that was about. It turned out in fact, to be the "mythical" third version that was supposedly only screened once in Texas. As you can see from the screens, both versions start out with Katie walking upstairs to the bedroom holding a knife and wearing a blood stained shirt.
The DVD screener version has Katie immediately sit down on the floor and hypnotically rock back and forth for several hours before the police enter the house. The alternate version has Katie close the door and look into the camera before slitting her own throat.
