Graham Booker is a lead dev with Perian. Have a look at his analysis of
the problem at his blog http://www.cod3r.com/tag/ac3/
The AppleTV does perform proper passthrough with it's much earlier
flavor of Quicktime, presumably to allow for true DD with HD rentals.
Graham strongly recommends that anyone affected file a bug with Apple -
he provides links in his posts.
