Which program to decode ac3 files on a mac? Pulling my hair out!

Care to elaborate? I already have Perian and am aware it allows quicktime to “understand” ac3s. Is that the extent to why I need it?

A 2 pop (or pip) is one frame of tone 2 seconds before first frame of program. It is an old industry standard way to sync separate audio and video.
Old film people like me grew up with it. The young folk of today, although terribly keen to add in scratches, grain, edge fogging and frame flashing that we tried so hard to avoid, should learn about the tried and tested ways to marry up sep elements.

Yes, Perian lets QT applications to read/decompress all these different kind of file so you can export to any other QT supported format.

There used to be a few little Mac apps that would do this, but none of them seem to have survived the Intel revolution. I keep falling on dead links while searching for them. Those that did survive, like More Missing Tools (https://www.angelfire.com/mac/rnc/files/MoreTools.html) don’t split the AC3, they just convert it or fold it down to stereo. I’d go for the clumsy method and be done with it.
You understood the FCP manoeuvre well. The 2-pop is just a sound that comes two seconds before the start of your program, usually to sync sound and picture. If you can find any sound that is present on all tracks at the exact same time (gunshot, hit, explosion…) you can check that your exported audio files are OK by checking if that sound is still well aligned on all channels. It’s just a safety.
