I just bought a Sony PRS-505 and put some .pdf books into it. The pages don't turn very fast and I've seen on reviews that .lrf files would speed up page turning.
Problem is, I can't find a .pdf to .lrf converter. I also have some books in .html that I've been able to convert to .pdf and put on my reader, but is there something that can convert .html into .lrf?
Basically, I have no idea what I'm doing and I need help please

Does anyone know where I can find a converter and if it is free to download or not?
Thank You!
