I have a bunch of e-books in Djvu format which I want to convert to EPUB for use with an Android tablet I just ordered. Since I couldn’t find any software converting directly from Djvu to EPub, I am trying do do it in two steps: converting from Djvu to to PDF and then to Epub with Calibre.
I tried many softwares ( PDF Lite, Nova PDF, A-Pdf to Djvu) . The conversion to PDF is OK, but I cannot get the final conversion to E-Pub in Calibre: the last (free) software I tried ( Boxsoft) looks very user friendly, but even with it I cannot convert to Epub. At least I am getting some symptoms of what is going wrong: when I load the viewer in Calibre , it takes a minutes or so for the Epub file to get loaded: it says “ loading e-book” then “ loading flow” and finally I get a page filled with black bars instead of the printed lines… Sometimes I also get a warning about a script problem..
Does anybody know what is the problem and how can I solve it? I don’t know if the problem is with Calibre or with software used to convert to PDF.May be I should find an alternative to Calibre.

Thank you for your help
