Rollover event not playing movie in buttons/gotoandPlay function not playing frames

Question

This web site has 7 buttons (each button plays a different movie/each movie(.flv) has a stop action at frame 1). The first 3 buttons (button set 1) exist on the timeline from frames 1 to 28. Frame 29 has a blank key frame for the 1st 3 buttons. There is action script for the 3 buttons in frame 1. Next 4 buttons (button set 2) exist on the timeline from frame 30 to 90 as well action script.
The stop actions are at frames 29,50,69,90. Labels are at frames 1,30,51,70. When testing the movie button set 1 functions as expected (the rollover event for each button plays its movie and selecting the button plays the correct frame) . Button set 2 is not working (the rollover event for each button is not playing the movie and selecting the button does not play the frame)
Using cs4, as3
This is my 1st attempt at an interactive project like this and am not sure how to make all the pieces work together. My action script is included below. I would appreciate a breakdown of why the movies are not playing as well as the gotoandPlay function for button set 2 and how can this be fixed. No errors are reported when I test the movie the buttons for button set 2 just do not function.
Thanks in advance.

Answer 1

Steps tried so far to troubleshoot functionality of buttons in 2nd set:
-         Recreated the .flvs for all buttons in 2nd set. Re-imported to flash and swapped with existing video
-         Thru event generator generated rollover and rollout code for each button
-         Commented out the stop action for each video (stop actions remained active on main timeline on stage)
-         Retested movie – video continuously looped on all buttons in 2nd set, GoToAndPlay function still not working
-         In addition to the commented out stop actions for each video also commented out stop actions on main timeline for buttons in 2nd set
-         Retested movie – Rollover functionality which causes the video to play works; GoToAndPlay function plays the correct frame but continues to play through to end of timeline
