How do I permanently delete my videos in imovie?

I'm having problems with thumbnails when loading imovie 09 so I decided to simply copy all my youtube videos onto an external drive.

When I went under "downloads" and "all movies", there was a bunch of cache and old video files. I deleted a bunch of them a few weeks but they keep reappearing!!! Why does this happen and is there a way to get rid of them all together? It's eating up my hard drive! Thank you.

FYI, I no longer import/export to my hard drive b/c of this. I use my external at all times but this problem is still present. Any help would be greatly appreciated!

I've also done a disk repair on my hard drive and it seems to work for now but not sure if this is a permanent solution.
