I have searched around and have not yet found an answer, so here's my scenario.
I have my xbox 360 hooked up to my living room home theater via hdmi. i have a second hdtv in my bedroom that is literally 15-20 feet from the xbox (bedroom and living room share wall). I have already tested and confirmed that the remote works from where i'd be playing in the bedroom (I had my wife watch the screen to see if my character was moving).
So what I want to do is be able to wirelessly stream the a/v from the xbox to the bedroom tv. Additionally, the living room tv is 1080p, bdroom tv is 720p, in case that will change things. Lastly, cost is a factor, i.e. cheapest way possible please.
