Fair enough.  So do I :-)

Thankyou!

I was also confused by the following comment:

setLabel("Commercial Skip Method");
addSelection("Blank Frame Detection (default)", "1");
addSelection("Blank Frame + Scene Change Detection", "3");
addSelection("Scene Change Detection", "2");
setHelpText("This determines the method used by MythTV to detect "
			"when commercials start and end.  You must have "
			"automatic commercial turned on to use anything "
			"other than 'Blank Frame'." );

I didn't know whether that meant the auto-flagging, or the auto-skipping
option.

I experimented last night and had better results with blank frame over
blank+scene.  Turned auto-skipping on for a lark and actually had it
skip properly a couple of times - much fun!
