[MX 2004, AS 2.0] advancing movie clip frames

I would like to control the embedded video by advancing the playhead forward and /or backward by increments > 1 frame.

I have tried:

on (press) {
stop();
for(var j = 0; j < 4; j++)
nextFrame();
}

  • and -

on (press) {
stop();
mc.gotoAndStop(mc._currentframe + 4);
}

(mc = movie clip)
I enabled Simple Buttons and clicked on the buttons containing the AS; they are not functioning. Although, the play, stop, goto first and last frame buttons work. I am perplexed. :frowning: I have tried creating a new .fla file with a different .wmv, and the failure to function persists.

Any Ideas?

I appreciate all posts!
