Since some parts of AC3 passthrough work, and others do not, I decided to create a bit of a compatibility matrix to summarize it. I’ve added the related bug id’s I’ve reported, which have gone unanswered, in parentheses.
The latest version of perian (to be released soon), will choose between using the hack method for [...]

Note: This does not work with all receivers. If these instructions fail for you, most [...]
