I'm not really sure what are you not being able to do, but watch the videos anyway.
If you think of the comp lanes as minitracks contained in a master track, that can be deleted, reordered, etc, it should not be a problem to get what you want. Remember that you must be sure that you are really selecting the right lanes or portion of lanes with the selct tool. You can even add an empty lane and move the clips of other lanes there, to create a single lane, and then delete all others. It will become a "uncomped" track.
