Looks to be tied to the ad call somehow. If a different ad call is used, the error does not happen and ads play.

In addition, a safety condition has been placed in the sync() function to stop the URL being set to null for holding clips - this ensures that the blank holding clip plays if there is an error.

Looks like the deliveryType="streaming" is causing some type of matching when it comes to pulling out the media type after the on demand load... the following debug comes up once the ad call has completed:

12:12:44 GMT+0100 Debuggable: Loading up the newly retrieved ad slot into the player playlist
12:12:44 GMT+0100 LinearVideoAd: Searching for linear ad SPECIFICALLY matching type: any, bitrate: -1, width: -1, height: -1
12:12:44 GMT+0100 LinearVideoAd: Could not match a media file for the given search parameters

Why is a match not being found?

Fixed in 1.0.1 RC2 (Build 25). VideoAd.getPreferredDeliveryType() was returning "progressive" by default - and in this case the VAST response was a "streaming" delivery type. "any" is now the default delivery type that is returned.
