For completion's sake, here's my blog entry covering my GreaseMonkey script "YouSift".

YouSift puts a link on YouTube(screenshot) and CollegeHumor(screenshot) video pages. When clicked, you will be redirected to VideoSift's submission page and all the relevant information (embed code, title, tags, description), if available, will be filled in automatically.

All you need for this to work is FireFox (SeaMonkey will work too) and the AddOn GreaseMonkey. If you have these two, all you need to do is go here and install YouSift.

Feel free to drop me a line if you encounter any problems while installing or using my scripts.

Enjoy.
