you have very good setup there mate, may I suggest that you have a look at the Raspberry Pi Model B , it's basically a small box(size of a cigarettes box) with HDMI and optical to your smart TV, and Ethernet to your router/switch, the box uses your TV Remote and it has XBMC interface, and it's DLNA enabled, so it will find all your shared folders, files, as well as there many futures such as movie cover, subtitles, plays web streaming and many plugins, and it can be also controlled via it's iphone/ipad apps
to me , it was best $50 spent ever.
cheers
