Interesting, but not surprising results.
Mobile video is a huge opportunity for brands to connect with consumers, but the network speeds and reliability have to improve considerably before it can be properly utilised.
Until networks can offer this, I think app publishers should look at ways to offer the user the chance to download the video they want to the phones memory, while they have wireless coverage, or overnight when the network is less busy. That way the play back experience will be excellent, as will the advertising opportunity.
