What's "button over video?"

[timmmay]

I did a search of it in the forum but can't find any clear explanations. What is it for? How do you do it for example in Maestro?

Did you perchance peruse the Guides on www.doom9.org. There; you will find a excellent explanation and implementation instruction.
