148288 flv video download script

I want the script similar to [login to view URL] from where users can download flv videos from different websites. I need for as much as possible as listed on keepvid.com. Also I want the facility to record the requests of the visitors for the videos in a mysql database and show the top requested videoes, recently requested videos and top requested websites on the home somewhere. Dont worry about the design I just need the backend code working. I would prefer someone who already has this script and can show me a demo. please pmb for further details
