I can hear sounds now, but still cannot view the video. I have tried the methods suggested above (except playing through HTML) but I still cannot view videos in .avi, .mpg, or .mov (with 'Use Enhanced Video' or without). I'm not a video whiz, so I am not certain about how to fix codecs if that is the problem.

Our primary use for MediaLab will be to display videos. I am using a trial version to see if our group would like to purchase it, so a speedy response would be much appreciated.
