some great suggestions! All of which I have considered at some point in the last 24 hours!

I don't have BD player - what's a safe way to go on that front? I have one more HDMI input left on my receiver - however, I am thinking about upgrading to a receiver that has pre-amp outs.
I have also been thinking about creating my own acoustic panels - so I might be able to do one big upgrade and a DIY panel addition.
Dave: you mention a Media server. What would I need to get that going?
