ePub Rendering - How to control where pages split

Hi Folks,

We are working towards using Arbortext (6.1 in this case) to render our traditionally PDF content into an ePub format. We have a somewhat custom schema and the rendered document looks pretty good - however Arbortext/Calibre seem to split the content into separate pages at seemingly random places.

Does anyone know if there is a way to control where the HTML content is split for the ePub format (or even how the point the page is split today is chosen). Otherwise our only option is to do post processing to reconstitute the file, and re-split how we see fit.

Thanks in advance,

Rob.
