Many older ebook reader devices are incapable of displaying
EPUB files that have internal components over a certain size.
Therefore, when converting to EPUB, calibre automatically tries
to split up the EPUB into smaller sized pieces. For some
files that are large undifferentiated blocks of text, this
splitting fails.
<p>You can <b>work around the problem</b> by either increasing the
maximum split size under EPUB Output in the conversion dialog,
or by turning on Heuristic Processing, also in the conversion
dialog. Note that if you make the maximum split size too large,
your ebook reader may have trouble with the EPUB.
