Not loading new episodes

[mylastsong18]

This might be something I've done but i am trying to add in a couple more podcast feeds and no matter what i do some of them never load any information about the episodes.

"AllFeeds.Add(new Feed(new Uri("http://feeds.twit.tv/aaa_video_hd.xml"), "All About Android", "Description", new Uri("ms-appx:///UI/StaticImages/aaa2048.jpg"), "TWiT"));"

Here is a new feed that i have added for All About Android from TWiT. No matter what i do it will never load the episodes for this feed. I have it setup exactly as the Windows Weekly is setup and it still won't work. If i hit Refresh Episodes while it is loading the whole app will crash. What could be the issue with this?
