Hi
I've just got my PRS-505 (£100 second hand on ebay bargain

) over the years I collected a fair few .lit files I used to read off my PDA. I've converted 30 or so into .ePub and sent them to the reader using calibre but they're all REALLY slow when changing chapter, I'm talking over a minute in some cases. It quite annoying because the first 6 or so pages are often separate chapters so that's 6 mins before I can start reading the book

.
Is it normal for the 505 to be this unresponsive on ePub files or have I done something wrong in the conversion/uploading?
