Hi guys. I'm hoping you can share all your knowledge with me so I can get my mom a good gift this Christmas. She has a HD tv with an HDMI hookup and a DVD player and Dish Network DVR box. She has a Macbook with lots of movies and music on it, so do you think an Apple TV is a good way to go? She already has a DVR and I don't know how Apple TV works. Will all her movies and stuff work with the device or does it only work with the media found in iTunes? Thanks in advance.
