Problems converting EPub to MOBI
I am using a Kindle (so need MOBI format files). I regularly download ePub files from my local public digital library (which uses Overdrive as a delivery platform) and then use Calibre to convert the files into MOBI.

In the past, I've had no problems at using this process, but recently I've had problems with a few books. Some work just fine, but others give an error message indicating an ODF error in the source file, even though the source ePub file is fully readable in Adobe Digital Editions. Have Overdrive changed their file format recently? Are they adding additional protection to stop us from converting? Is there a solution?

I attach the error log.

Can anyone help?

Can you open the imported epub with calibre's book viewer?

Actually, having now tried; no, I can't read the epub book in Calibre, but I can read the same file in Adobe Digital Editions. Odd!

Okay, that says DRM removal which not a topic that we are allowed to discuss in depth on MobileRead. Have you installed the DeDRM plugin? See the New version of DRM removal tools ("DeDRM") thread for a bit more information. The latest version is found at Apprentice Harper's github page.

Good luck.

Thanks; that seems to have done the trick. I was using UnDRM previously but lately it seems to be not working with some files - maybe the publishers are getting wise!! I wasn't aware of the Calibre plug-in and not only does it work, it is much easire to uase that having to pass through UnDRM first. Thanks, again.

I would advise you to use AZW3 instead. It gives a much more readable result than MOBI.
