Video Downloader Chrome Extension - Any Recommendations?

I have to download tour trailers for a number of sponsors who don’t send out affiliate content. I had been using a Chrome extension (I don’t remember the name), but it had been compromised in some way and a malware detector deleted it.

I’m currently using MuGet HTML5 Downloader, but it doesn’t work on every site. So far I’m unable to download Military Classified and Chub Video.

Do you have a Chrome extension that works?

Our users turned us onto Internet Download Manager https://www.internetdownloadmanager.com. I have a copy and it works very well.
