All 1890 ebooks in our collection have now been completely refreshed, and should work on the Sony devices.
It seems that while other readers are a little fault-tolerant when it comes to the epub spec., the Sonys were not. The main problem seemed to be the inclusion of qualified dublin core metadata elements in the content.opf file. Most readers (and sensible programmers) would simply ignore something as inconsequential as dc:date.modified, but not the Sony.

I also note that epubchk flags as an error the existence of .png image files, which it calls "non standard". Well, if a reader baulks at that, too bad. No way am I going back and replacing png with gif or jpg.
