Thanks for the response and suggestions.  Good catch on the space before *.ai. 
Unfortunately, removing that didn't make it download the absolute links, but
it did correct the errors.  I'm using WinHTTrack, and don't see the raw
command line output anywhere, but I do see the status in the log.  That said,
I tried the following scan rules:

-mime:*
+mime:text/html
+mime:video/*

and

-mime:*
+mime:text/html
+mime:application/x-mp

All of these get the index page, but the absolute links are never downloaded. 
Any idea what I may be missing?
