Interesting thing happened on the way to breaking the rules .. It may turn out to be a bad idea to cross the streams. Here's my topology: SWM is all DECA connected with passthrough on HR21-200 to the LAN as shown I started the following recordings: (Streaming in direction of arrow) HR20-700(WB68) --> HR23-700 HR23-700 --> HR21-200 HR21-200 --> HR20-700(WB68) With 3 of the receivers streaming, the 4th box HR20-700(SWM) could barely hold a torch. two resets and it couldn't even connect to the Internet although it showed local area IP number. I could not get the local playlist to show up on the HR20-700(SWM). I stopped all of the playbacks, left everything alone for a while, then came back to the "bad" HR20-700 and it then connected to the Internet fine. I'll spend some quality time testing on Saturday (after new CE) as I will have free access to all receivers. My initial observation, though is that crossing the streams could prove problematic, especially piping 3 streams through the HR21-200 internal Ehternet switch.
