is it possible to stream video from my macbook to my hdtv over a draft n network? what equipment would i need to do this? thanks everyone!

sure, you could stream something like a video_ts over a "g" network, let alone "n." (Granted, real world wireless performance can vary.)

But, you'd need something networked at the Westy to act as an extender--to receive and play back the video--and that could be another Mac, an aTV or a host of other devices (PCs, networked media players, etc.) it just depends on what kind of video you're interested in.

Are you recording high def yet? If not, you will, so you may want to think about wiring with gigabit anyway.
