How to check if a video(from megavideo,123video.nl etc.) is working or not

[siddscool19]

How to check if a video we embedded on our site from megavideo or any other hosting site is working or not using a php script?

I just want to know what all things i have to use

I know how to use curl so it won't be much problem explaining

For example:

<object height="351" width="432"><param name="movie" value="http://www.megavideo.com/v/N5SEN8Y570c24971658d4740c0b991c1b4779bdc.6307685858.0"><param name="wmode" value="transparent"><embed src="http://www.megavideo.com/v/N5SEN8Y570c24971658d4740c0b991c1b4779bdc.6307685858.0" type="application/x-shockwave-flash" wmode="transparent" height="351" width="432"></embed></object>

Now how to check using php if the video is working or not
