I tried to run airvideo on a windows vista 64 bit system (in 32 bit mode) but nothing works. My firewall settings are all checked, but the video server does not run (When I type in the browser http://my ip:45631/ I get no connection). Itunes is installed. When I type in the local IP adress on my Iphone 3GS (no jailbreak)I get an Communication Error: timed out. What can I try next?
