I use YTSaver. I'm on a mac. (There's a PC system too) It was a one time payment for lifetime use. It works like a web browser, you log into your OF and there's a download button. It's a little clunky, but it works. The thing is, it seems to only download from messages or from the wall. It doesn't seem to work when I go to download past DRM protected content from "Purchases." But no biggie. It's only for vids, not images. Apparently, Chrome on an Android Phone also downloads DRM protected content for those who have Android phones. (I don't). So there's a few solutions. Personally, I don't buy anything I can't download.
