I installed Allvideo 4.4 on my joomla website 1.5. The flv video's all works very well, but when I try a mp4 video it will not play. Only a black box with circles.
I hope I can get an answer here, I searched a long time for the solution.

I found out that the video first have to been downloaded and then it works but that will take a lot of time.
Is there a solution for that the video play at once? Maybe there is a parameter to must set or anything else?
Many thanks in advance!
