Ok, here's what i've found on the "Unknown" author thing.
I extracted the .epub file and edited the "metadata.opf" file and found that there is no info on the author.
<package xmlns="http://www.idpf.org/2007/opf" version="2.0" unique-identifier="calibre_id">
<metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns

I also found differences on the "toc.nx" file. Whe converting, i told the program to keep the original TOC or index from the source file, but it still converts it. Here is an extract from toc.nx original and converted.

The chapter names are replaced by the book's title and so they show up in the table of contents when opening the file from the sony reader.
Also, the "playOrder" variable starts from "0" in hte original file and now starts from "1" (not sure if this is important).
