OK, done with AV upgrades for now.  Removed the old DVD/VCR player and put a drawer in it's place using the removed cover from where the new TV was placed.  Rebuilt the storage area behind the double glass doors, adding a place for the DVD player, moved the antenna switch from down by the floor to this area, added a place for an HTPC, and created space for DVD's. Put a AC outlet down by the floor where the antenna was previously at.  I went with a sound bar and wireless sub-woofer for audio.  I added a usb WiFi to the HTPC and connectify software to automatically switch between my tethered phone or wireless if available. I added a wireless router connected by Ethernet to the HTPC to rebroadcast WIFI for the coach.
