doesn't work with the site xhamster anymore since yesterday.
It seems that from December 1st the downloading function on xhamster is only available for premium users. Nevertheless, downloading the clips is still working on Firefox with the Download-Helper extension. Maybe the developer(s) of Flash Video Downloader can include a function to extract the video-stream out of the browser-cache of Chrome?
This is the error message given when using the plugin on xhamster.com:
Access to file 'filename.flv' is forbidden: key is required
I see the same thing, and politely beg for a fix :-)
