Yes, I know, I should search for the answer, but the problem is that I dont know where to begin.
This is my problem:

I have a Sony prs 505. I have a few books in pdf that I want to put into the reader. I used Calibre to do it, but when I read them in the reader there is a lot of problems: breaks in the middle of the line, the original page size doesnt fit into the screen and the begin of the capitel in in the bottom of the page, It lost the original format, etc.

I dont know what to do and how to do it. I hace a mac, so I need a program that can make the right format for my ebooks. Could anybody help me?

thanks
