Menu looping incorrectly

Hi all, I imported a 1 minute quictime video (with audio) to place it as "background" on each of my menus. I want to see my minute-video (with audio) looping every 1min. However, as soon as the video hits 5 seconds it starts again from cero, so I can only see and heard the first 5 seconds of my 1 min video. Also, once I press the main menu and go to the next menu (which contains the same video as background) It displays it for 9 seconds and loops back to cero. Both times are different and they do not match the real time of the video.

My question is: is there a setting that I'm missing concerning background looping? or is this a DVD SP bug?

Any feedback is always appreciated.

Thanks
