1- Copy the link of the page where the video you want is on.
2- Go to Javimoya.com, paste the link in the bar and choose from which site then click submit.
3- You will see a new "Download link" button in the middle of the page, ctrl-click and download the link to your desktop. It will download a file with ~~.flv extention. Note that in some cases the file will download with the extention of ~~.flv.txt (note the .TXT at the end), when this happens simply rename the file by removing the (.txt), you'll be permitted to change the file extention, choose (.flv).
4- Now that you have the file on your desktop, download Wimpy FLV Player, it's a free application that can run FLV and SWF files directly from your computer.
5- Run the application then drag and drop the .FLV file in it.
Simple? Yes indeed.
