Best Settings for Converting Epub to HTML

Hi guys,

I am looking for some advice. I need to convert epubs/Mobis into HTML in order to convert them to another platform.

I have found that the default settings usually convert quite well, although some problems occur with regards to TOC and headings. These problems is intermittent and perhaps depending on the quality of Epub/Mobi file. I was just wondering what is the best settings for converting from Epub/Mobi to HTML. The various settings are quite daunting and I feel a bit overwhelmed.

I am hoping that someone has some tips for the best settings for converting Epub/Mobi to HTML. Any ideas or tips?

Thanks
