Any good "scene detection" programs out there?

Hello,
I know there are a few programs out there with "scene detection" features, but I haven't come across one that actually works yet. Anyone have any luck with these? If so, which program?
Thanks

It will do "optical" scene detection

Many DV editing programs do scene detection from metadata added to the DV tape by the camcorder as you start and stop. If you were to dub say a TV show to your DV cam, the metadata wouldn't be there to breakout the scenes.

Scenalyzer will attempt to detect the scene through image analysis.

Thanks ed.. should've mentioned this in the first post, but I'm looking for detection for MPEG-2s. I'm assuming there's no way to import an MPEG-2 into Scenalyzer?
