Thanks for the recommendations. I looked briefly at Kodi but wasn't sure whether Netflix (my primary source of video entertainment) plugged into it. I'll have another look.
Also consider something like a Roku. I mentioned plex earlier, which plugs into the Roku as a "channel" - I use my Roku 3 with Netflix, HBO, Hulu, Plex, and a few other things here and there.
It's not a free replacement like Media Center but it works really really well, and is worth the price if you are a regular streaming media user.
I believe both Plex and Kodi should have plugins for Netflix. NetfliXBMC should be Kodi's, and Plex should have it as a Plex Channel, which you can set up on the server.
