    I have a new macbook with the latest OS, I'm burning my itunes music folder to a disc. I notice that the folder burned to the disc is slightly larger (in bytes) than the original folder in itunes. It's still the same 4.18GB size, but if you notice the bytes on the burned dvd compared to that on the original itunes folder, the dvd bytes are higher. I even tried burning a second one, after restarting the computer, and the bytes match the original dvd I burned. Why the discrepancy between the original folder size in bytes on my computer and then one I burned onto a disc?

    If you burned the files onto a DVD in a normal ISO format, then I think the extra bites might come from one or more .DS_Store file -- OS X uses them to preserve some aspects of metadata when it cannot be stored in a non-native filesystem. The same files get automatically created when files are saved on FAT16/32 USB drives.

    As you've probably already guessed, it's not something to be concerned about.
