Generating titles of pdfs

Hi Lester,

I have one problem… If I add some pdf the plugin reproduces that same file but title of that particular pdf is {title of pdf – url of that same pdf}. For example if I add PDF with url (file name) lester-chan-made-great-plugins.pdf and title Lester Chan Plugins Are Great the plugin generates me Lester Chan Plugins Are Great-lester-chan-made-great-plugins.pdf. My question is what I should do so plugin can reproduce only title when pdf opens, without url (and the minus sign before url in title) in title bar?

Thanks
