If this dosn't work, try to diagnose exactly how the size is wrong. You can do this by making a skydome image with regular squares on it.
i will try this with the squares it seems like a good idea i have tried many different resolutions 2048 x 512 being one of them
but on a different note do you know where the settings for the image or where the settings for the enlargement of the skydome animated?
