What.... ?
Are you referring to "Digital Video Stabilization"?
It's in camera settings under the video options.
I know, before was there, but there was an app update last saturday, and option disappeared
The option is still there for me on my 830. So, it's either a bug with the update or something particular to the 520 which caused them to remove it. Can't help beyond that, sorry.
What ShaneRay said, unless more specific information comes to light.
