This issue was up in another thread. I got a file and modified mobi2mobi to be able to analyse this. I had some ideas of things to test and the person giving me the file did test some of them. I did not here that he succeeded with this.

mobi2mobi can be used to change some of these values but since i do not have a Kindle I cannot test it to try to find out how it works.
