My RSS loader stopped working after a couple weeks? I never changed anything

I’m loading RSS 2.0 feeds off myspace, it use to work perfectly and had a response time under half a second.

http://www.iceflyin.com/personal.htm

Now it sometimes only loads the first blog or sometimes two or all. It’s very strange.

I decided to go check if myspace had changed their RSS feeds, and I don’t think thats the problem… I sure do wonder whats with the “itunes” thingie… <itunes:author> Maybe thats fouling up the LastRSS class?

Very strange… Heres the full feed: http://blog.myspace.com/blog/rss.cfm?friendID=79255902

I’m using LAST RSS. I just had to modify the first part to get it to work with AMFPHP.

I don’t get what the problem is… It seems like the PHP script randomly gets caught in a loop and only returns the content parsed before the error occurs.

This use to work perfect… Just one day I started having problems, most people seem to be able to load my blogs fine. AMFPHP is working perfect for my MySQL-PHP-Flash Shoutbox.

Something must have changed that is causing this class to take up to twenty seconds to parse Myspace Feeds… AND doing it incompletely half the time. LoL…
