Components in SWF, then loaded into another SWF

I have a main movie that contains 7 buttons. These buttons, when clicked, call to external SWFs to load on the stage in ‘placeholder’ clips. I have a press section. In this press section I have 2 videos that I am loading using the MediaPlayback component. They are visible on the stage when the appropriate button is clicked inside the ‘press.swf’ file. There are 2 buttons on the main timeline of ‘press.swf’ , one to load each of the videos. I have 2 MCs in the library (video1, video2) that I am attaching to the timeline via ‘attachMovie’ when the button is clicked. Inside each of these is the component with the call to the FLV that should load inside the component. I have this working correctly. When I preview the ‘press.swf’ file in Flash it works great.

Then I go and open my main ‘index.swf’ file. When I click on the button for the press section it correctly loads the movie. I try and click on the 2 buttons I have to load the movies and the videos do not show up.

I have seen the “this._lockroot = true:” suggestion. I have added this code in various places with no good results.

Is there something else I can try to make the components show up and work? Thanks in advance.
