(Get the code!)
The burners burn in blocks of 32kB each.
When iso's are not exact multiples of 32kB they pad the iso's with 0's when they write them.
The burning software calculates the MD5 checksum on the original, unpadded iso image
The MD5 sum calculated after burning includes the padded zeros and will not match the original MD5 sum calculated on the iso if the size of the original iso was not a multiple of 32kB.
