Videojs safari crash on fast forwarding

videoJS sounds like a nice solution and we almost accepted it, but there are two glitches in my attempts:

first, that Safari 5.1.7 on macOSX 10.6.8 (all the latest in this line), click to fast forward (i.e. to the right of the cursor) freezes Safari: rainbow waiting wheel keep spinning
the second is that the same attachment just doesn't display anything on MacOSX 10.7.5 with Safari 6.0.2

None of this happens in Chrome or Firefox. And that doesn't happen on videojs.com.

However, the code is pretty similar, the video files are copied (I hope everything is ok): here you can play: http://direct.hoplahup.net/tmp/videoJSattempt/video-iframe-attempt.html and source:

<html><head><title>videoJS attempt</title>

    <link href="http://vjs.zencdn.net/c/video-js.css" rel="stylesheet">
    <script src="http://vjs.zencdn.net/c/video.js"></script>
</head><body>
<video id="my_video_1" class="video-js vjs-default-skin" controls
       preload="auto" width="640" height="264" poster="/tmp/videoJSattempt/oceans-clip.jpg"
       data-setup="{}">
    <source src="/tmp/videoJSattempt/video/oceans-clip.mp4" type='video/mp4'>
    <source src="/tmp/videoJSattempt/oceans-clip.webm" type='video/webm'>
</video>

</body></html>
