Today version 0.77 build 58 is released.
One important added feature is the ability to use Comskip to edit the cutlist.
Drag and drop the .txt file onto comskip.exe. The debugwindow will open with black bars below the video where the commercials where detected.
Look in debugwindow.rtf for the editing commands.
