We gave this a go some time ago, but compared to the job Hi-Def Digest did, ours is pathetic. Not only do they go into detail about what every audio format available for both HD disc formats is all about, but they go on to give examples of discs that include them, and to top it all off, how to enjoy them. It's more complicated than you think because not every player or connection method supports every audio format. To be honest it's far more complicated than it should be and we wonder how anyone could make heads or tails of this mess without being very dedicated. Lucky for us, Joshua Zyber is up to the challenge and his article should help clear things up for just about everyone.
