OK I can stream stuff from my (All Android!) Tablet, Smartphone or Sons Smartphone to my 2 Smart TV's and All-in-One 3d BRD Home theater system. (no Apple TV, Roku etc required). My son can stream stuff from his smartphone to my tablet, vice versa appears to be possible but not yet tried. However I cannot seem to find a way to bring our PC's into the loop either streaming from PC to other device or streaming from other device to PC. All are on same wireless N network.(When my son is visiting!) Most info I find says that I need to load a "Media Server" onto our PC's. I must confess I do not see why this is necessary? Furthermore the free Media servers recomended all get stamped on by my anti-virus and anti-malaware monitors.
