The prior builds required manual naming. So if you used my XML, it was me who renamed them 3x and 10x. The current Arnova and BSG 8.1 builds autodetect the values from the Camera IDs themselves. The true zoom value is 2.9x and 9.9x rather than 3x and 10x. For Arnova, you can just go to GCam settings > advanced > aux config to rename the buttons.
