If anyone's interested, I know Telestream's Tempo (http://www.telestream.net/tempo/overview.htm http://www.telestream.net/tempo/overview.htm), is super popular as it can actually cut and/or interpolate frames from content, to allow content producers to run more ads, without any perceptible difference from the viewer perspective.
