This is not a DNS issue. This is the justin.tv widget doing something fishy in the background.
I have Little Snitch installed and locked down so it can't make any connections, but it tries two different sites over SSL in an attempt to fetch content for the frame.
I assure you, I do not have malware.
It happens when the justin.tv widget in the side-bar loads. It attempts to load something that redirects to http://rts.pgmediaserve.com/03d458/
