YouTube: video plays, can hear audio, but image is spinning wheel on gray screen

[gallagth]

Running cheapcast on my Nexus 7 (first generation) with Android 4.3. YouTube videos autoplay but most of the time there is only audio and the video shows a spinning wheel on a gray screen (sometimes the video starts correctly though, but rarely and I can't tell why).

I've looked at the logs in depth and I couldn't figure out why this is happening.

Play music works perfectly, Play Movies not at all (it sends 5 POST events and then gives up to play the media locally)
