Scene Detect in CS3?
 

I have a 2 cam wedding ceremony shot with A1 and hv20. The problem is one of my videographers hit the pause button a couple of times and it is very difficult to see where and thus my multi cam edit does not match.

Is there a quick way to find out where the breaks are?

Use HDVSplit to break up the captured file as a scenedetect mechanism after the fact.

Im sorry, I forgot to mention that i downconverted from HDV.

Will HDVSplit still work?

In that case try Scenalyzer.
