I think you'll find that only HTML files can go in the spine, and that the toc.ncx navpoints likewise can only reference HTML files. I always make a Coverpage.html file and link to that.

You don't mention how you are producing the ePub - by hand, by Sigil, or by InDesign. If you are producing them by hand I'd be happy to send you examples of files that I know work and validate with ePubCheck and FlightCrew.
