I currently have a regular (not high speed) cable going from my Apple TV to my AV receiver. Would I get full 1080p quality if I replace the current cable with a high speed one? My TV is a full 1080p tv and I do use a high speed hdmi going from my AV recover to my tv just didn't know if I also need a high speed hdmi going from Apple TV to av receiver. The new ability to watch HBOGO movies just doesn't look as good a quality as I am used to on HBO from my Directv satellite box which is also connected to my AV receiver but that connection has a high speed hdmi cable. I just don't want to go to the expense and trouble to replace my plain hdmi from Apple TV to av receiver if it is not going to make a difference.
