The small sized "5000k" color temperature doesn't show up when I disable the firmware , So there is no way to actually compare both cases. I suppose that this info is given by the addon. However as I said, when I set the camera on NTSC (I wrote SECAM I'm sorry for the confusion) on my PAL TV the problem disappear. Has the addon been tested on PAL systems ?
Also I tried different settings 16/9, 3/2, 16/10 in ML menu but the L/R sides are still cropped.
