Youtube video download changes?

Hey all I was using this class to download and convert my youtube videos.

It seems as though youtube changed something, so now I can't download the videos anymore. It has something to do with the SetFlvUrl function. I think they changed the embed code or something that grabs the actual video url. Any ideas?

I take it you did not write this yourself. I doubt someone is going to fix it for you if it's broken, perhaps finding the original author and seeing if they can fix it?

 

But anyway, do you get any errors or anything? Or does it just not work at all?

[ballhogjoni]

I did write some of it. It used to work as of Sunday (a few days ago). The problem is this line

if (eregi('fmt_url_map',$file_contents))

it no longer finds the match. This leads me to believe that Youtube changed something on their site. I am not looking for a rewrite of the class, I am looking to see if anyone has knowledge of the change and how to fix this line/function in the class to make it work again.
