I see that vlc is mentioned. I did have a problem yesterday when, through vlc's UPNP functionality, I was unable to play a video stored on my NAS. I can't be sure whether that is related to this warning because I parked it and got on with investigating my resume problem. I've had few goes at playing the video this morning and I still can't get it to play via upnp, but the warning hasn't appeared, so this may be a read herring.
