Windows Media Player problems

Hi,
I have sent you an example questionnaire file (to support e-mail address), all individual files have the same problem so I have just sent one example.
Thanks!

Got it. Try this super-simple test questionnaire. It's basically an instruction screen followed by a movie with no parameters at all. That's it. This will simply help us rule out any explanations that have to do with the content of your experiment.

To test it, rename one of your .wmv clips "test.wmv" and put it in the same folder with this que file (after unzipping it!). Run the clipTest.que questionnaire and see if the test clip plays ok or if you get the same problem as before.

Thanks..
I ran the test file as you said to and the some problem occurred, intermittent play but audio intact.

Hi there,
I have discovered some more clues to the problem that might help you work out what is going on!

The first time I run a questionnaire after starting MediaLab the video file doesn't seem to work. However if I cancel out of the questionnaire (by pressing Alt right arrow), and then run the questionnaire again (without exiting MediaLab in between) the videos seems to work thereafter.

BUT if I open MediaLab afresh, and try to run the questionnaire, the video won't play. If I let the questionnaire file run its course (without pressing Alt right arrow), and then play the questionnaire file again, the video still doesn't work.

It seems as though the video will be able to play, but only after I have cancelled out of the questionnaire using Alt right arrow, and this needs to be done WHILE A VIDEO IS PLAYING.

Anyway hopefully this might give a clue to what is going on, but I'm not sure, I have tested out this theory a few times, but it is also possible that playback is working randomly and I am just seeing patterns when there aren't really any!

Also - another way to get the video to show up once it has started but the screen is black is to put another program window (ie internet browser) over the top of the MediaLab screen, and then take the other window away again. THis can only be done if Medialab is being played in a small screen (for my experiment I would prefer to have the MediaLab window at full size).

Can you make any sense of all this?? Thanks.

A while back I think another user had a problem that sounded like this (i.e., trouble with the first video only). I think it turned out to be a problem using the "Enhanced Video" option on the Preferences Menu on their particular machine. Do you happen to have that option turned on? If so, try unchecking it and see if that makes a difference.
