A long time ago, I found this post online with some tips for finding files in the browser cache. Specifically, Flash videos. However, I'm currently running OS X 10.7.2 and Safari 5.1.2 and this method doesn't appear to be accurate anymore.
I also tried the RealPlayer Downloader method mentioned in the comments on that link, but it's not detecting the videos in the browser.
Can anybody think of an updated version of this? Where might I find Safari's cache items to copy them?
