I just bought a VXS 822 K's from Wal mart for $218 with free shipping. I hooked everything up but haven't run a cat 5 to it yet from my router. I tried to do a firmware update from a USB thumb drive but it doesn't see it. It says it isn't hooked to a network. Is there a way to do the update with out connecting to my network? Another problem I have is it only plays my Sony Blu ray if it is connected to the cable/sat or DVR/BVR Hdmi inputs and not to any of the other inputs. I want to use those inputs for my Comcast DVD and my TivoHD. Any ideas?
