Google Video and Dailymotion must have recently made some changes to their websites and for the moment are not working correctly with Flash Video Downloader. As I have mentioned, FVD queries http://videodownloader.net to find the FLV file to download. As a result, if videodownloader.net cannot download a file, than neither can FVD.

I've double checked and videodownloader.net cannot download Google Video or Dailymotion. I just send videodownloader.net an email telling them that these two sites are not working anymore, and hopefully they will fix it soon.
