Hi,

I discovered this community some weeks ago when I tried to decide wich reader I should buy. I finally decided to go with the nice little Opus. I love it.

But…

Lots of books I would like to read don't exist in epub/suitable format, but I foolishly thought I would be easy to convert them…

So yesterday I bought a book in prc format and I am stuck, because I have to remove the DRM (it's legal here for personal use) before making the format conversion.

I try to use the python script mobidedrm0.5, but I don't know how to find the Opus PID…

How can I find it?

Please excuse my english, and thanks in advance for your time and your help

Only MobiPocket devices have a PID. The Opus does not support MobiPocket, therefore it does not have a PID. QED.

Download and install the Windows desktop version of the MobiPocket Reader, register the PID for that with the bookstore, and use that.

Thanks for your help Harry,

The store didn't ask me anything about a PID when I purchased the book :huh2:

I have a mac, and I just discovered the lack of mobipocket reader for mac :smack:

First and last mobi book that I buy…

Some ebook stores (I'm told) don't ask for a PID, but get Mobipocket Reader to re-encode the book after download. I'd try for a refund if you didn't get a warning that Mobipocket Reader or Windows was required.

1. Are you sure the book is DRMed?

2. If it is, I understand that to encode the book so particular device can read it, they need to encode it with PID of this device. Since you didn't get asked about the PID, it might be as pdurrant says, that they send you the unencoded book, and Mobipocket Reader encodes it on your computer. But it also needs the PID to encode it.

So:
- if you can read it in Mobipocket Reader, maybe you can get the information about its PID off it? or
- maybe you can give it a PID, any PID, and get it to re-encode the book with it? Then you'll know which PID it's encoded with, and can run the script.

You need the Mobibocket Desktop software. Virtualbox or Bootcamp is your friend :)

If you are going to remove the DRM, you don't need an actual Mobipocket device - you just need the book to be encoded for a known PID.

Which bookstore did you buy the book from?

If you only want to run MobiPocket desktop, I wouldn't recommand such a tool like VMWare Fusion or Parallele desktop, but CrossOver, it doesn't need a Windows licence. But all of the three software require an Intel Macintosh..

Thank you all for your advices, it seems like a nice community :2thumbsup

I bought the book at numilog, and didn't notice the "what are your PID" field on the form.

But I am pretty sure the book is DRMed, otherwise I could open it and convert to another format easily, right?

I am the worst case possible as I don't even have an intel mac ahah…

I'll try to ask a friend to install Mobipocket Reader on a PC and give me the PID, then redownload the book, and retry…

What a @ª†º¬å∑∂ just to read a 10€ book , that I legally bought, on my own device. What are they thinking…? They treat their customer as thieves anyway, I would better just get an illegal pirate version :angry:

Thanks again, I'll let you know how it went…
