I set a ~30-sec MPG for a menu background, set it to "Auto length detection" and set it to loop. At the end of the clip I get a black flash before it starts the clip over. I verified that the clip itself does not have a black frame at the end or beginning.

I went in and set the length to manual and cut it back a fraction of a second, and no longer get the black flash.

It appears that the auto calculation of menu length is not accurately calculating the length and making the length slightly longer than the clip.

P.S. I tested it w/o an audio track just to guarantee the audio track wasn't causing it to be calculated longer.

if you can't reproduce the problem, I can send you the MPG and the DAR file.
