Just a quick follow up. I think I now have my issue figured out. I am not sure what was dropping the ball, it was either the router or the bluray player or the dlna software, but I do know why it was dropping out. Seems if you run other programs with UPnP port scanning abilities (ie bit torrent) it can mess with your system. Stop using that software and the DLNA runs smooth and nice. I am able to stream 720P video with ease to my Samsung machine.
Thanks for the help. Thought I would post in case people with the same issue do a search.
