trouble with controlling servos

Here is a thread where I show running 18 servos.
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1265626147/6#6

Separate power supply for the servos.
Ground connected to Arduino.
Signal pins from Arduino to servos.

And the thread with a movie of the hexapod.

edit: I guess I left off the link to the thread with the movie: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1267069898/0
