Thanks for your interest, everyone.

Nice catch on the hardware unit, David.

Appreciate the windows Audition 3 tip, Gary (I kind of gave up on the Adobe 2 and 3 angle until I saw that).

And Eero, I appreciate your sharing you experience with the software decoders.  I want to learn more about what is meant by "logic" features.

I may not get to work on this much for another few weeks though.

Stay tuned...
