I have seen many people asking for a software which can download any video or mp3 while steaming it. Well guys there is already a software which does this and its here since ages. Use IDM (Internet Download manager). Basically this software is free for 30 days but who cares if it is for 30 days. The trick is to uninstall it after 29 days and clean the registry . Restart and Install again. Tricky but works everytime like a charm.This software works on almost 90 percent of all audio and video streaming websites. The only area where it fails is for playlist tracks that many website render via flash and it is almost very secured !!!!Apart from that you can use it on YouTube, Metacafe, e-snips and almost all such websites.Enjoy and post back if you have any problems.PS: Works with chrome like charm

For Users Who are having problem integrating IDM to Chrome:

1. Go to Customize and control google chrome
2. Tools
3. Extensions
4. Get more extensions
5. Download and install Download assistant
6. Go back to extensions
7. You will see download assistant clip options
8. Slect IDM
9. Save & close

P.S: I dont know if this problem is caused by some sort of bug or the default download manager cannot be changed, BUT this trick works for sure. Enjoy

thanks for shearing such a useful information.
