I hate writing docs. :)

Auto-skipping is disabled if you don't use the auto-flagging option
in current CVS.  The on-the-fly detection is nowhere near as accurate
as the auto-flagging thread and I hasn't been worked on in quite a while.
If you are using software-encoding, then blank frames are always detected
at record-time whether you have auto-flagging turned on or off.  When you
turn on auto-flagging, the code will fire off a commercial flagging thread
after a recording finishes.  This code is better than the detection done
at record-time and is necessary for good detection when using hardware
encoders.
