I will Fix this issue in the next few days

Here is the feature request to vote up: http://thebeebs.userecho.com/topic/160856-/

So that feed won't work. It's only playlist URLs that are supported... E.G. the ones you can search for using the system. I will add "Support Channel Videos" as a feature request. The you tube video issue that other were experiencing has now been fixed. The issue was caused when a video had no comments or likes.

Yep I will make this more prominent on the documentation here: http://zipapp.co.uk/Help/Download

Instructions on how to create the appx file are here: http://zipapp.co.uk/Help/Download

I know.. I will fix when I have the blog platform live.

Ok Working on this. You shouldn't be able to add an Application without filling out a description.
