Thread:Extension talk:HTML5video/Can't get video to play

Playing a youtube video works fine but playing the internal sample video (bunny.mp4) doesn't appear. The extension is installed here: $IP/extensions/HTML5video/HTML5video.php

The sample video is here: extensions\HTML5video\videos\bunny.mp4

The usage is: bunny

Yet nothing appears on the page. Any ideas what I might be doing wrong?

Thanks!
