Closed Captioning and pause bug

Hello All,

I currently have a problem with captioning on a video file that I am streaming from Flash Media Server. For some reason, the first time the video is viewed, the captioning pauses right around 6 mins. I've verified this happens from multiple computers, from different physical locations and on different networks. The video continues to play, but the pause button on the playbar also looses functionality and the captioning does not progress.

I've created a total of 11 videos all using the Flash CC plugin with a custom button for show/hide captions and minimal playbar which only includes the pause button and the mute button. This only happens in this one particular file, but they are all setup the same. From what I can tell, the xml is constructed correctly (TT XML generated by contractor). The code I've written works fine on all the other files. The only thing I can see that's different among the files is possibly the size of the movie I'm streaming. Its the longest.

If the viewer refreshes the page and watches the movie again, the pause does not happen. Is it possible that a setting may need to be changed on the Flash Media Server?

I'm asking for possible roads to go down in fixing this issue. Any ideas are welcome. Thanks in advance.
