I try to use the movie option to use with questions. Locally it works fine, but after I copied and past it on a webserver it do't display the video. I tried to make the video as small as possible.
I used video also with Presenter and embed a video from youtube/vimeo with the "webobject"option. Such a feature would be great to use in a question. If I embed video's on youtube they are played fast and I don't have to worry about formats and sizes.
