Embedded youtube clip doesn't work [iPhone 4]

[davidspivak]

Hello,

I hope you guys can help me or perhaps refer me to some place where I can find help regarding my problem.

I am running an experiment as part of my Psychology studies. This experiment includes showing an embedded youtube clip to participants via their own iPhone. Now here's the problem: one of the participants is reporting not being able to see the embedded youtube clip (it's working for the other particpants). I'm afraid her iPhone may be too old for the clip to work, or maybe the embedding code I'm using may be not readable by the device.

She is using an iPhone 4.

Her browser meta info is as follows:
Browser: Safari iPhone
Version: 5.0.2
Operating System: CPU iPhone OS 4_2_1 like Mac OS X
Screen Resolution: 320x480
Flash Version: -1
Java Support: 0
User Agent: Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_2_1 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8C148 Safari/6533.18.5

Here is the code I'm using:

<object height="100" width="200">
    <param name="movie" value="https://www.youtube.com/v/XNVCJb2p3j0?modestbranding=1&amp;title=&amp;version=3&amp;hl=iw_IL&amp;rel=0&amp;fs=0&amp;probably_logged_in=0" />
    <param name="allowFullScreen" value="true" />
    <param name="allowscriptaccess" value="always" />
    <embed allowfullscreen="true" allowscriptaccess="always" height="100" src="https://www.youtube.com/v/XNVCJb2p3j0?modestbranding=1&amp;title=&amp;version=3&amp;hl=iw_IL&amp;rel=0&amp;fs=0&amp;probably_logged_in=0" type="application/x-shockwave-flash" width="200">
    </embed>
</object>

Any clue?

Thank you,
David
