I can see this bears watching and I have some work to do I can do now before I get it back
See my above post and you may not have to go through all of this complexity. Use Calibre to convert epub to epub and redownload the book to the NC. For any that do not work with this, use Calibre to convert from epub to MOBI and then back from MOBI to epub again, and then redownload. This has worked 100% for me without having to use anything other than Calibre conversions.
