how to replace a video with a new version

I created a new version of a home video. I deleted the old one from iTunes and then imported the new one....I thought. The old version keeps showing up and I can't figure out where it's coming from. I deleted the entire video library, said to delete the file and closed iTunes. Then I went to the iTunes folder on my hard drive, and deleted all the files in the home video folder. The opened iTunes and imported from a separate folder where I put videos after they're created in PremierePro.

Still the same versions show up. There must be a copy somewhere, but I can't find it to delete it. HELP.
