There's a part of the file missing.
Most likely it is caused by not syncing the camera file system after
editing that file and rebooting the camera.
The safest way to sync this file is to save it through
> 192.168.0.9 -> Parameter Editor
Or (in case of editing other files) this can be done from the telnet
session with a command "sync".
Also, you can change parameters with a http request in the following way:
