Just bought first Apple (21" iMac). Looking to serve up all my DVD movies, TV shows, etc. I am trying to figure out best resolution to rip (I use DVDFab on PC). Apple TV states max of 720P for H.264 yet iTunes sells HD content that is 1280 x ?. So would ATV stream this 1280 HD content anyway? If so I would rather rip to a higher res than 720 if possible so I have the largest that I can afford to save on HD. Any opinions please ?
