I turned off the network connection on Friday and so far I haven't seen any problem yet. I believe the network connection is the cause for my HR20 box problem: BSOD and RBR. I had to do RBR twice before I could turn off the network settings. Hopefully I won't see a lot of RBR again. Until I can stream video from my PC and the network feature becomes more stable, I will keep network setting in my box off.
You might want to give it a try and see if it solves your RBR problem...
