What type of books are you trying to convert? Are they PDF, .lit, mobi .... etc? Oh, and do they have DRM attached to them (proprietary coding to prevent them from both being converted and being used on a different device than the one the book seller wants you to use...).
i am not sure about the type of the books as the person hasn't showed me books yet... so i dont no.. but as soon as i find out ill post it...
