Thanks both for the comments. My Playon trial had expired and due to the fact the few Netflix movies I tried with my HR21s' looked very soft on my HD sets, I will not use this service for now. BTW my setup is Uverse, the switch and the gateway almost identical to yours.
atp1313, I still don't fully understand why you can't get the Netflix to stream to your HR2X. Maybe a firewall issue? Have you been able to get it to steam yet? It's odd that Hulu works and Netflix doesn't.
New issue: each folder (Netflix/Hulu/YouTube/CNN/etc) is now saying that "there are no files in this folder". I am putting some stock in this HR20 needing to be rebooted - I have already rebooted the PC. Since there is a CE tonight, it will get a full boot then. I will report back any changes in connection tomorrow.
But as for the streaming of NetFlix not working, I had read some posts on other sites (including PlayOn's site) that Netflix's SilverLight player has some streaming issues outside of the Netflix environment. Don't know the tech specs, but it has been mentioned.
