Firefox Video Downloader addon
This addon will allow you to download practically any video you will come across on the web as long as you let it buffer completely.
This nifty little program will play videos in almost any format. The reason you will need this is because video’s downloaded with the firefox video downloader addon will be in FLV format which can currently only be played with the VLC media player.
You could go and convert the videos that you download to wmv or avi format to play in your windows media player but this will take ages. Just get the VLC player you will come to love it… trust me 
Whats next?
1.Now that you have the programs necessary. Go to a megavideo hosted movie or whatever your watching let it buffer completely. This may take a while depending on your internet speed and the size of your video.
2.Next you will need to right click the video. You will see the “Download video” option appear. Click that and wait for the download to complete.
3.As soon as the download is finished right click the video and open it with the VLC media player and hey presto! You have just got past the megavideo download limit and you will have the video saved to your harddrive for future use!
