apple tv to directv hd receiver on an older tv that does not have hdmi
I'd like to get apple tv so I can watch Netflix in my bedroom. I have an ipad2, directv hd DVR downstairs with internet connect so my DVR communicates with the HD receiver upstairs. I also have an Xbox 360 connected to the HDTV/Directv DVR downstairs. My bedroom has an older TV (not hd) and I have the directv hd receiver hooked up to it. What will I need to do to get apple tv up and running on the older tv in the bedroom?
Apple TV, Windows 7
