So here's the "horror'" story you've been wanting to hear
I convert my pdf file to lrf using libprs500 and send it to my prs505 (main memory). I plug out usb, start up my ebook reader and select the file i uploaded. It starts formating for 5 sec or so and walaa iam done. But here's the catch, the paragraph ain't formatted properly when converting from pdf to lrf..
so in PDF it would be
(words)
(empty line)
(words)
in LRF it would be
(words)
(words)
...etc
and also when theres a double empty line it ignores that too

So how am i suppose to do a flawless conversion?
