I just upgraded to Windows7. Any thoughts of using MediaShare or TVersity or PlayOn are gone forever!!! My Sammy is fully DLNA compliant and with Win7 I can send any media directly to my TV without even using the menus on my TV!!! I just right click the file and select "Play To" and the file is played right to my TV. The only thing that I have found so far is that I can't send files from my NAS (Buffalo LinkStation), they have to be on my local hard disk. My TV also has recently added Blockbuster as a widget and I can stream movies without any additional software. Windows7 Media Center has added Internet TV and not only is it free, it works perfectly. CBS, CW, Showtime, Netflix, FOX and many others are all available. I'm really lovin Win7 and my Sammy!!!
