Stream instance null?

[Gregory]

So I have a sony NSZ-GT1 which runs google TV. On it I'm using an application called "Media Player" that came on the device. It connects fine and I'm able to browse the files with thumbnails no problem. When I go to play a file it tells me that the Stream Instance is null. In addition to this if I go into the transcode folder and do the FFmpeg one, the file will play for about a minute or two and just stop. No matter what file it stops at the same time in. I have attached the trace log of the null stream instance. And I could try some other things if it helps.

I'm not sure what I should do to try and get this working. Thanks for your time.
