making NTSC / PAL changes persistent

Using the video camera for skype as mentioned earlier, the NTSC setting was not being saved in the video source settings - it was reverting to PAL on reboot, when skype restarts. Googled and found a solution here. Downloaded VideoWDMControl v2.2, put it in the startup so that as soon as the machine boots up, the source can be set. But still, it would be better if the changes could remain after a reboot.
