# Example 2
Before: 1309853696
After: 1316044800 which is divisible by 2048 but not 1024^2
For the record, I had lot's of images that were similar to example 1's
1263595520 bytes in size, and they all ended up as 1266693120 bytes
after isohybrid:ing them. Also note that the padding is 3097600 bytes
and 6191104 bytes, respectively.

Agreed. But we now have a report about failure of 255x63
on a popular pseudo-hardware, when the ISO is presented
as DVD-ROM. (Probably there is no complaint when it gets
presented as hard disk.)
