thought I would provide an update.....Ok, got my new BD670 today. DVD playback no longer an issue. Mezzmo now recognizes my device properly but streaming still does not work. I have a Belkin N+ Router and get high packet loss with the LG for some reason. I am not seeing this behavior with any of my other WiFi devices including a Samsung B series tv which streams from Mezzmo pretty well. All firmware is up to date so I am thinking there must be an incompatibility between the LG and the Belkin N+ Router but have not found anything documented yet.
