Playing Video in MediaLab

[melovetrees]

I am attempting to have Ps view a video file in the midst of questionnaires. MediaLab keeps telling that there is an error. I have tried using 5 different formats, with no luck.
Any suggestions or help would be greatly appreciated.

Have you tried using a different clip altogether--e.g., a short mpeg or avi downloaded from the internet? If so, do you have a small sample clip you could attach along with the que file? I can try to replicate the problem here and help to troubleshoot it. Also, any specific error text that you can report would be helpful, including error message #, title, and message text.
