I AM CONFUSED. Which one is true of these two statements? Some said even N is not enough for HD movies streaming, Some said (Local store staff, some people on forums) that N is enough to stream full hd movies, and G is enough to stream 720p movies. Please guide me. I am saving up some money and planning to buy a home entertainment system mainly used to watch 720p movies, consists of : - NAS WD Mybook Live 3TB - WIRELESS ROUTER Buffalo WHR-G125 <--- already have - MEDIA PLAYER ACRyan PlayonHD Mini + usb wireless adapter Is this even possible without problems like stuttering or delaying or whatever else I don't know yet?
