I’ve just started with FCP Studio 5 and while I did a practice ac3 encode with compressor, it was for a stereo track. I’m guessing that using Compressor in FCP Studio 5 to make ac3 tracks is similar to apack with FCP 4.5.
In apack you need all 6 separate tracks that comprise the 5.1 signal. It seems as if these have been supplied to you. They are probably labeled as to their 5.1 position (left, center, right, etc.).
You open apack and tell it you’re encoding a 5.1 track. It will open up with places for all your audio tracks. You simple drag the appropriate track from your finder to the corresponding box in apack. See the Ken Stone article for clarification:

After you’ve laid out your tracks and adjusted the relevant parameters (448kbps, dialog norm -31, and Film Compression off) click Encode, tell it where to put the file and you’re done. You just marry the resulting ac3 audio file with the mv2 file of the video in DVDSP (or other DVD app) and you’re done.
