I really know more about computers than I do TVs and connectivity, etc. I have a fairly new HDTV which has one HDMI port. Currently I have this hooked up to a Blu-Ray player. What I am wondering is if in order to use an Apple TV I will need to either hook up the Blu-Ray player with those other cables (yellow, blue, white, red, whatever) and then use the HDMI for the Apple TV or if I could simply unplug the HDMI cable from the Blu-Ray player and pop it into the Apple TV when I want to use the Apple TV? Obviously I wouldn't be using both devices at the same time anyway. I just want to make sure that no harm would come to either device by swapping out the HDMI cable. I'd really rather not have to fiddle with the multi-colored cables at all if I can avoid it. Also....different scenario, too: a friend has a FIOS connection for her TV and internet. She also has a combo VCR/DVD player/recorder device. I am not sure how that is hooked up to her TV, whether it is with an HDMI cable or with the aforementioned colored cables. She, too, is interested in getting the Apple TV and probably in a couple of weeks we'll be going to the Apple store to get her one. Since she is even less knowledgeable about TV connections, I know I'll be the one nominated to tinker with the installation of the Apple TV. Last thing I want to do is to screw up anything with her FIOS connection or her combo VCR/DVD player/recorder! Any advice and suggestions gratefully received! Thanks!
