Comskip1
Ilya points to a really cool (and free) commercial detector –

Comskip is a free mpeg commercial detector. It is a windows console application that reads a mpeg file and analyses the content based on a large amount of configurable parameters. After analysis it generates a file in various possible formats containing the location of the commercials inside the mpeg file. The formats include input files for interactive video editors (VideoRedo, Cuttermaran, Mpeg2Schnitt…) command line video cutters (mpgtx, cuttermaran, mencoder) and video players (zoomplayer, mplayer, …). Comskip can read MPEG PS files upto HD resolution (max 2000×1200) at 25fps (PAL) and 29.97fps (NTSC).
