Media render not recognized errors

[reapshot]

I have an issue where every time I try to play a video from my Android phone using via Upnp using the Media Monkey app, I keep getting the "server inaccessible" message and the video won't play. If I wait a few seconds and press play again, the video will start playing somehow but then it ends up crashing a few minutes later. I can't do any seeking (forward or backward) for that video either or it will freeze up and crash.

This is some of the logs

This isn't maintained, you might have more success with JUPnP

Is that another App, or is it a setting?
