in which I've suggested a likely cause for the problem (that the cover isn't actually ending up in the book), but he's not yet replied to my post.

Well, I've noticed some interesting cover behavior with the Kobo (which is nearly identical to the Sony in this area), and how Calibre generates covers.

Calibre can do one or two things:
- Update the meta tag in the OPF for the cover image itself.
- Insert an HTML cover page at the front of the ePub.

The Kobo, like the Sony, ignores the meta tag, and instead uses a rendering of the "cover" page from the ePub. It seems like there are quite a few situations where Calibre won't replace the existing cover page, and rightfully so. That said, I've had Calibre refuse to replace a cover page it created and had some odd/blank covers due to the size of the cover image and not using SVG to scale the image. I have one which simply shows a blank cover which I can always poke at tonight since I was going to fix the ePub anyways.
