I'm using a Radio Shack A/V broadcaster to beam TiVo from one floor to a TV in another room. The TiVo has a linksys usb wireless adapter attached. The oddest thing is that when our computer wireless network is off (airport express), I get interference in the visual-- broad bands of moving snow. When it's on, it transmits fine! Any explanations of what seems to be a counter-intuitive problem? Any solutions other than leaving the wireless network on 24/7?
