tvml player crashes

I'm having unpredictable player "crashes" in my TVML app. I'm playing multi-bitrate stream files from a wowza server (which works perfectly well on iOS). When streaming on-site of server I have not been able to duplicate the crashes. However, when I take the device to my house, the playback will randomly "crash" and kick back to the last screen before playback began. It seems like it's some sort of buffer underrun, but that's mostly conjecture. My house is only 12 miles from the server and I have significant bandwidth in both locations. Has anyone else seen a problem like this?
