Videos dont progress after playing (case 5526)

[raypark70]

I have been trying my ML2010 to play video files properly but failed. Not sure what is going on.

What is happening is, after playing a video file, MediaLab 2010 won't move on to the next item. It will stop, displaying a small square on the screen (see image file attached). Only after I use the hidden control key (ctrl + right arrow), it will move on. But after playing the next video clip, it will do the same.

I have two systems (1: Win XP SP3, 2: Win 7) running the latest ML2010 (ver. 3.1). Both are doing the same.
Video files I have tried using are .avi and .wmv -- both doing the same thing.

I am also attaching the Questionnaire file for you to review. Though nothing fancy here, I am suspecting that parameters (which orders the system to shoot out TTL signals) *might* be playing a role here. I am not sure but even if it was the case, I do need those TTL so I cannot give that part up.

Any suggestions are welcomed. Thanks in advance!
