How do I delete videos from itunes??

I have a few duplicate videos in my itunes "video" library.. and can't clear/delete them.

I dont want them to go on my ipod as duplicates the next time I update, any help would be greatly appreciated.

thanks.

you must do it from the library, not the video playlist

i'm an idiot, thank you

You can delete from any playlist by holding either option or command (I can't remember which one) and pressing delete. It will ask you if you want to keep the file or not (I click on no).
