i think this goes here, it's about ePub output!
anyway, today i got calibre and started converting some of my PDFs to ePub to put on my ipod, because i prefer how epubs act on my ipod to pdfs. anyway i converted 7 in total, 5 of them worked perfectly and are on there with no problems all fine.
But 2 converted without text and read like this


any ideas as to why? or how i can fix this?
thanks in advance!
