Yes, it's called Windows Media Center. Obviously you need a MCE 2005 or Vista PC with a TV tuner card to do it. I've watched live content streamed wirelessly to my xbox 360 (which I do because the 360 is hooked up to my 720p projector onto a 100" diagonal screen in the basement...PC is upstairs). I've even used the MC remote that came with my PC to change channels using the 360 as the extender. It works flawlessly except for HD contnent...the 54Mbps limitation of using the adapter in A or G mode definately is not enough throughput for High Def. Would be nice if a wireless n adapter were offered, but since the 2nd draft was just submitted it's not supposed to be finalized til 2009 (although MS could certainly offer something earlier, but it wouldn't be compatible with all 802.11n WAPs). I don't watch much live TV using the 360 as the extender though, mostly use it to watch Recorded TV from my Vista PC on my bigscreen.
