Diagnosis
The problem is that we are firing the impression tag in the JS before we send the XML to the VPAID SWF. The VPAID player SWF then fires the impression tag again. We just need to change the sequence so that the impression tag does not fire until we know that the ad is not VPAID. No biggie, but I’ll need to do some testing to make sure I don’t break VAST impressions while we're at it. - LB
