First off- if there is a better group to post this to, please let me know.

I am preparing to network my home A/V system with my current wired/wireless 
home computer network in order to play music and video from the hard drive 
as well as streaming content from the web. There have been "Media Bridges" 
available for a while now (ex: Linksys WMB54G), but recently a lot of high 
end A/V receivers are coming with a network (RG-45) connection built in.
Any opinions on which way is better?
