That’s actually a problem with the TVDB database.
The database contains a URL to a file that doesn’t exist, and the XML Fetcher is unable to proceed since it thinks there is a file, but the server can’t find it. :(
What makes this especially bad in this case is that the error is with the VERY FIRST EPISODE:
http://www.thetvdb.com/?tab=episode&seriesid=73096&seasonid=20561&id=333022&lid=7
If you open up that URL, you’ll see an Episode Image there, but the image is broken.
You’ll need to contact the TVDB folks and have them correct the database for that series. You do that by posting in their forum, and just tell them “Season 0 of series 73096 has lots of broken Episode Image links.” It can take a while for them to get to it, though… so just be patient.
