See menu in background during mp4 playback

I have encountered a strange issue. I finally mamanged to get an AppleTV compliant mp4 file on the machine. It play back. But then all of a sudden I see that the menu of AppleTV can be seen through the video. The white letters are readable very lightly through the video. Has anyone else have such an issue.

I am using 3.4.5 of ATVFlash.
