This may not be the answer you're looking for, but I quit using BTV's Smartchapter generation because it was not very accurate. I started using Comskip to generate smartchapter files and it has been FAR more accurate and faster.

I have instructions for this in a write up I did. The link is in my sig.

*EDIT* My write-up includes steps for video fixing and commercial removal, but these are optional. If you only want to do commercial detection, you can just use the Comskip portion of the instructions.
