How many people out there have the 2nd Gen Apple TV? Thoughts and opinions about it? how often do you use it? is there a way for me to connect and external HD to a apple tv so i can use my mac to select which movie i want to play but not actually have to hook up my mac to my tv to play the movie? or have to hook up my computer to the external drive to play the movie? Simply put id like to be able to: Turn on my mac, sit it on my lap select a wireless external HD, click on a movie watch it on my tv! while still being able to surf on my mac. Also, do i even need an apple tv to JUST play movies? if my tv has a usb input can i hook up my tv to a external HD and use my tv remote to navigate through my hard drive? Lastly, if i do have an apple TV, can it played movies that are NOT in iTunes? for example downloaded stuff from internet and ripped files? Lastly, where is the bottleneck in connecting a HD to an apple tv? What will make it choppy where like the movie still has to stop and buffer then keep playing? Is it the HDD rpm rate or the speed of a cable or the speed of the Apple tv? Is there a certain cable or is the internet the determinant factor if ill be able to watch movies without buffering if my apple TV is connected via usb or whatever cable it uses? I really want to buy one tomorrow so any quick useful responses would be greatly appreciated!! thank you to everyone that helps this uninformed apple lover out!
