YOu should try another downloader for Firefox such as FVD. @ addons.mozilla.org

There probably haven't been changes on the YouTube website to cause this because Video DownloadHelper is still working.

Do the videos still display properly?

Try Youtube (VEVO) video and audio downloader https://addons.mozilla.org/En-us/firefox/addon/youtube-video-and-audio-dow/?src=ss

I have tried 8 yes EIGHT video download programs all none work...the ones that DO download a video put it in a format that won't play on Windows Media player at all....very unhappy....

Try a player like VLC or MPlayer if the WMP can't play the files.

I find the best and easiest by far is to use firefox download helper. Follow the link for easy instructions on how to install and use download helper. This works on all free video sites and also on You tube which now provides some full BBC and ITV TV programmes. https://www.youtube.com/watch?v=SW-gV1Dnh_Y
