I might be totally missing something here, but I never used to have this problem. I am getting an "ID invalid" error when trying to verify my ePubs most of the time. (The files work fine, but I need them to get through the ePub verify unless Apple has loosened up their rules.)

After experimenting, it seems to boil down to when the random ID that Calibre assigns to the Cover file in the content.opf file starts with a number. If it starts with the letter, then it is a "legal" ID and it verifies properly.

If I manually change the ID to start with a letter, it passes. But that is a bit of a pain, of course.

Anyone know more about this and if it can be fixed automatically through Calibre?
