Is there a network outage or some other systemic issue?  I have a Samsung PN58C8000YF plasma and a Panasonic Bruray DMP-BDT300 which are both having issues.  I can connect and stream Youtube videos just fine.  But I cannot log into my Youtube account on either...I get a network connection error on both devices.  They are both updated to the latest firmware and both have a stable wired connection to my network.  I have no problem logging into the website from a computer using the same credentials I attempt to use on the connected devices.  I am not getting a "wrong password" reply...but a network error reply.  The credentials work fine for the google calendar app on the plasma, so I know my authentication with google is fine.  Any ideas?
