I also observed this that the Video Profile 3 is locked for mydlink.com.
The setting for VP3 is 512Kbps, so it will choke my internet upload.
No matter how I set video profile 1/2 to their lowest bitrate and resolution, the iphone mydlink app crawls to slow because it is using this protected Video Profile 3.
So this is an error on the firmware. DLINK, please allow us to change Video Profile 3
