I'm running Premiere 5.5. and I cant seem to figure out how to export a Quicktime with 4 channels of audio(2 stereo pairs), any ideas?
You can't...yet.
This ability will be new to CS6 when it actually get's released. For now, your limited to mono, stereo or 5.1.
Good to hear, I look forward to CS6
We all do.
Here's a video about some of the new audio features:
