Which version of Video DownloadHelper are you currently using (4.9.4)?

You can try to reset the dwhelper prefs on the about:config page to see if that helps.
You can open about: pages via the location bar like you open a website.


Version 4.8.6 can be found here: https://addons.mozilla.org/en-US/firefox/addon/video-downloadhelper/versions/

Some recent changes at youtube made the various quality variants to be not detected. This version fixes the problem: http://www.downloadhelper.net/install-beta.php?version=4.9.5a2
