I just got a new Panasonic Blue-Ray system (DP-BD655P-K) and a Panasonic HD TV and its says I need a Dy-WL10 wireless adapter to stream video from PC to TV. If I get that adapter and watch Youtube videos on TV via PC and Blue-Ray. Can someone else use the computer for something else or do I have to stay on the youtube page until I'm done? Plus, does the computer turn off while I am watching youtube on the TV? Plus, can I use a Belkin wireless usb adapter instead of a dy-wl10 adapter?
