Sorry, I keep forgeting that you are working from a Mac computer.
The following at the ccleaner web site seems like it would target your computer operating system...

The feature with the Set In and Set Out points which can be used to trim the video is just called Preview Window. Most of the time, users add to the description "Preview Windows with the Set In and Set Out points" to get across the idea that he/she is not referring to the Edit Mode Monitor in the workspace.
Do you have any video footage that is not .mod standard or .mod widescreen? If so, please give it a try to see if we can pin point the slow aspect of your workflow....video format versus computer versus other.
Thanks.
