Wow, I didn't expect this question to draw much attention! The drive is 
large, so maybe the reserved root space is the reason.

Here is some more info on the system:

Files system is ext3 under 2.24.26.

Per df:
   Filesystem           1K-blocks      Used Available
   /dev/vgusb2/video    180621680   6635676 164810964

The df used result equates to about 6,480 MB.

 From Mythweb status page:
  Total Space: 167,428 MB
  Space Used: 15,440 MB
  Space Free: 151,988 MB
