Are you using a proxy server or do you have any other extraordinary network setup?
Please keep pinging "services.tvrage.com" while retrying to use "script.tv.show.next.aired". After that please check if you still have "IOError: [Errno socket error] (11004, 'getaddrinfo failed')"-Errors.
I had another look to you xbmc log and found much more other network errors:
Code:

So there are:
- python errors when trying to open a webpage (not in this snippet..)
- xbmc errors when trying to open addons.xml.md5 files
- xbmc errors when trying to load the rss-feeds
Its not just a DNS-Issue - looks like a general network problem...
