I'll throw my 2 cents out here,  I had good success with a refurbished
pair of linksys powerline adapters.  I believe they were rated for
200mbp/s, I saw speeds of 60-70mbp/s while keeping an eye on them.
Was much easier than messing with wifi, and worked very well for HD
recordings from my HDHR and HDPVR.  Unfortunately they could not
handle 1080p content, so that may end up being a deal breaker.  It is
worth noting I am in a new home, any home with older wiring most
likely would not see the same results.
