i am working on a project that plays more than 22 mini-movies synchronly when the site starts.

the user can mute the sound of each video by clicking on it.
clicking again on a muted video sets the level up again.

- whats the best format to use? .flv files?
- is it the best was to set the level to 0 and the to level 100 again when a video is clicked?

it gotta be like a multi-channel music track.
you can turn on and off various channels to change the song.

who can help?
