The main objection we find when using these websites is that we can't find a download button to enjoy those videos offline.
FLV Downloader fullfills that gap. It's very easy to use. You only have to copy the URL of the video and paste it in the text box in the interface of FLV Downloader and click download. That's all
You can even add several videos and they will be enqueued.
The interface will not surprise you with graphics, but it works pretty well and, finally, that's what we want.
It supports webistes like Youtube, metacafe, dailymotion, break and more.
The program shows some ads on the left side, but they don't interfer its performance.
