I get an error message every time I sync my Apple TV to iTunes. Two podcasts I purchased on iTunes "...can't be transferred to Apple TV because they can't be found..." I trashed these two files over a year ago because I no longer wanted them. However, I want to delete these two files in the library directory but I can not find them anywhere in my iTunes library. How do I delete them if they no longer exist? I do not want to see this error message every time a do a sync.
