Excellent; I'll take a look at those and give this another shot.

I was working from a 1.9GB MrSid file; I had initially generated a
tiled GeoTiff (without overviews) and it comes in at 28GB.  However I
ran gdal2tiles on the MrSid file.

I used all the default options so I ended up with zoom levels 9-17 for
this particular MrSid as well as the default rendering options.  I'll
give it another shot with one of the higher quality ones.
