The Linksys WMB54G is a handy little gadget that hooks to your AVR via S/PDIF or L/R audio that will allow you to use your audio system as wireless remote speakers. Basically, what ever audio would come out of your PC gets redirected to the WMB54G instead, via your existing WiFi network. It works well and being digital all the way to the AVR means the sound quality is excellent. What does this have to do with an HR-2x you might ask? The WMB54G also has an Ethernet port that would allow you to use it on your wired network if you don't have WiFi. It is also used for initial configuration in some cases. It also has an undocumented use: It will act as a wireless bridge to the rest of your network. I hooked the Ethernet port into the uplink port of an 8-port switch that my HR-20, HR-21, HD-DVD player and Yamaha RX-V2700 are also plugged in to and voilà! My living-room network segment is now bridged wirelessly to the rest of my network and it took ZERO configuration. Both my HRs access VoD and are seen by TVersity, which is on the other segment. And my Yammy's network features all work as well. I was finally able to remove the bright lime-green CAT-5 cable that was running down the hallway. And the best part of it is that I used equipment I already had. So if you happen to already have one of these as part of your home theater system, and you have an HR as well, there you go. No gaming adapters or wireless bridges needed. And if you were considering spending the money on a WGA or bridge, you might want to consider the WMB54G instead. It's about the same price and has the additional benefit of being able to play your PC wirelessly through your stereo system.
