Unsupported URL error with a specific free GDC Vault video

[3id0]

Hello, I'm getting an "Unsupported URL" error with a free GDC Vault video. I've tried downloading other GDC videos and I only have the issue with this one. The error happens with both URL types : 'http://gdcvault.com/play/1020791/' and 'http://evt.dispeak.com/ubm/gdc/sf14/player.html?xml=201403828316_AJKF.xml&token=3c6c000ab0766078310c'.

Verbose output :
