# expr \( 4700000000 + 16383 \) / 16384 \* 16384 4700012544 Apparently, while being written, the image is expanded to the next multiple of 16k (might be even 32k or 64k). A single block on DVDs is 2048 bytes, I don't remember how big a group is (data needs to be written in groups due to error correction codes).
