@reyalpI'm not sure if the active area patch was correct. I can not see any bad areas in my DNG files with the old code. When you are correct also the SX230 is affected!
The SX220/230 was in last years one of the most successful canon models. Many people use CHDK with this cameras. Nobody else has reported this issue in last two years.
I see only some shodows in the corners. But this is because of the lense distortion. Here are my Files with the old code (DNG version 1.3)

@nafrafThe video capture works fine. There is no OSD problem. But it could be usefull also rework the code for the SX220. I think it is better we have an uniform code with the SX230.
CHDK for the SX220 works fine. There is only one Problem. The option 'super fine' for JPG files is not useable. The file size is smaler as with the option 'fine'. It seems to be a memory problem - read more ine the first pages of this thread.
I also have the feeling, in some cases the file size of the JPG file is smaller as without CHDK. But it is quite difficult to demonstrate this concretely.
