This is a 320x240 sized player with the same setup as above but using a call to double click as below. The advert does not play and the debug output from FireBug refers to an XML parsing error with the response from doubleclick.
I do not have confirmation that we are using the correct url to call the advert.

All firebug output from loading the OVA / advert.
