    video display problem in MediaLab v.2012 (case 11606)

    I'm running a CRM experiment to collect some online rating for a series of video clips. My clips are all in .wmv format and my initial parameter setting was (w900,l80,t120) for all clips which worked perfect on a desktop computer with a 4:3 monitor. But because I need to run the real experiment on wide-screen laptops, I changed it to (l.2,t.3) make the video display a better fit on the wide screen without having to try out different number for the dimensions. But the problem started which was that sometimes some (not all) clips would show in a teeny tiny window on the very top of the black display area in the center of the screen. I did test run on several different laptops in our lab (all of same brand, model, and configurations) and the problem occurred randomly, each time with a different clip and on a different computer.

    I changed everything from the percentage format (l.2,t.3) back to the (w,l,t) format but the problem persisted, although it seemed to be occurring at a less frequency, only one out of the total 17 clips. Yesterday my professor advised me to try using (w-2) for all clips. That fixed the problem but temporarily but it came back later today. Still, just one clip with wrong display throughout the entire experiment.

    Due to the randomness of the problem I don't know how to trouble shoot it. I had literally tried every different parameter combinations suggested in the manual but nothing seems to make the problem go away. What's the source of the problem??
