it worked for me in the beginning then youtube made some changes. the software didn't deliver after that. i had also tried the firefox addon which refreshed the page (as often as you liked). haven't played with this since. i haven't asked if others were able to make it work since the changes.

if you come up with a way that works, let me know.

i tried JMo's idea of putting your video as a video response to videos going viral (over 500,000) with minimal results.
