Auto-transcode does not remove commercials, you need to edit the recording
and create a cut-list first.   You can get a head-start on the cut-list by
loading in the commercial flagging results by pressing "Z".

Commercial flagging works 95% of the time (in the US anyway), but I don't
think it could ever be 100%.  You should always manually check it before
making any permanent changes.
