I've used this code
<iframe width="640" height="480" src="http://www.youtube.com/embed/....?rel=0" frameborder="0" allowfullscreen></iframe>
to embed a youtube video.
I would like to automatically set the quality to the max available (which in my case is apparently 480); what happens is:
1) Firefox 12.0: the starting quality is never 480, sometime 360 sometime 240 (yes it changes from time to time)
2) Safari 5.1.4: there is just one option, 360. Why?
I read Youtube - How to force 480p video quality in embed link / <iframe> but even if I increase the frame size nothing changes. The javascript method also seems to be not reliable.
Thanks.
