In the code where MythBoxee goes out to retrieve data from thetvdb, and it passes the name of a show as part of the URL request, consider adding a call to urllib.quote() around the show name to escape characters properly in the URL. One of my favorites is Law & Order, and without the ampersand escaped, it doesn't come back with the correct banner. Adding the above method solved it for me.
