Sound but no video

[similar issue edited from support email]

I am running MediaLab 2004 on my laptop and the computers in my advisors lab here at Purdue. I created a video that I would like to show participants (a .wmv file). The video plays in my questionnaire on my computer, but when I copied the files over to the lab computers the video does not work properly. I have sound but no picture. The video plays in Windows Media player on the same computer (which is what I thought played it in MediaLab). Am I doing something wrong? Do the files have to be in a different format (mpeg, mov)?

Does the same thing happen with other wmv files or just this one? Are you using the Enhanced Video option on the Preferences menu? Finally, you might try updating your versions of DirectX and of the Windows Media Player. Also, do you know how to generate a dxdiag.txt file?

I think I figured it out. I converted the files to .avi and they work now. It must be that we are using an older version of Windows Media Player and there was a problem interfacing. Thanks for your help!

I recently exchanged an old computer for a new computer. I copied all of our old media lab filed onto the new computer. Both computers are running the same version of all programs.

All of our old computers were running videos as .wmv fine, when I exchanged the new computer it would play the sound but not the video. I tried to change the file to a .avi but the same thing occurred.

The video works in windows media as well as real player.

I was unable to find the enhanced video option under preferences to try this route. Is this in the experiment editor?

Thanks
