Sorry - beginner with iMac - but keen to learn! Having created a slideshow on iPhoto, I am keen to find a simple way to display it on my living room HDTV - as a quicker & more effective alternative to burning it onto a DVD first. At the same time, I want the best quality picture possible on my HDTV, as I'm using an 18 megapixel camera. Will Apple TV deliver this for me - or is a media hard drive a better option? Alternatively is burning to DVD still the best way to show my efforts to family & friends on an HDTV?
