Can someone tell me in plain english what the avformat not monolithic error is and how to fix it? This is on XP SP3.

It's not really an "error".
FFMpeg can be built in different ways, monolithic or not monolithic. The "error" is that Audacity is unable to load the monolithic build of FFMpeg (because you don't have it). When that fails, Audacity looks for a non-monolithic build (which you do have) and loads it successfully (as shown in the message "FFmpeg libraries loaded successfully.")

very good.
