I'm pretty new to the sony reader and the ePub file format. I was used to the ease of use the mobipocket Reader software offered.
Calibre seems to be the only real choice for ePub conversion out there right now, but I've had some problems with file conversion from HTML and PDF to ePub with Calibe throwing out errors along the way or producing files that don't work very well on the Sony Reader.
However, I made a very interesting discovery today...I was trying to get a lengthy .pdf file into ePub format for comfortable reading on the Sony 505, but it never really worked with calibre (did no want to handle the 3900 Page PDF properly).
What I did was the following...I threw the PDF file at mobipocket Reader and then took the .prc and converted it to ePub in Calibre...and voila...the file is only half the size (down from 16MB to 7MB), all the formatting looks fine and nothing seems to be missing.
I have not checked the entire file of course (it's over 6000 Pages on the Reader after all), but as far as I can tell this combination seems to do the trick.
I guess Mobipocket creates a clean base for Calible to work with and everybody is happy...although I would like to eventually have something like Mobipocket Reader for ePub files...maybe Calbre will be able to fill that gap eventually...
